Dynamic Effort Method for Power Athletes: Build Explosive Strength and Bar Speed

Published: Strength Training Guide

Want to know the secret behind powerlifters who move heavy weights with lightning-fast bar speed? Or why elite athletes can generate explosive force in milliseconds? The answer lies in the Dynamic Effort Method—a training approach that develops rate of force development and speed strength using submaximal loads moved at maximal velocity. Here's what you need to know to harness explosive power and break through strength plateaus.

What is the Dynamic Effort Method?

The Dynamic Effort Method (DE Method) is a training approach that uses submaximal loads (typically 40-60% of 1RM) lifted with maximal speed and explosive intent. Popularized by Louie Simmons and Westside Barbell, this method develops rate of force development (RFD), explosive strength, and speed strength—the ability to move heavy weights quickly. Unlike maximal effort training where you grind through slow, heavy reps, dynamic effort work emphasizes rapid acceleration and bar velocity.

The key principle: it's not about how much weight you lift, but how fast you can move it. Dynamic effort training bridges the gap between maximal strength and explosive power, teaching your neuromuscular system to produce force rapidly—a critical quality for both athletic performance and powerlifting competition.

Key Characteristics of Dynamic Effort Method

✅ Load: 40-60% of 1RM (varies by exercise and accommodation)

✅ Reps: 1-3 per set (low reps to maintain velocity)

✅ Sets: 6-12 sets (higher set count, lower reps per set)

✅ Rest: 30-60 seconds (incomplete recovery emphasizes speed)

✅ Intent: Maximal velocity and acceleration on every rep

✅ Primary goal: Develop rate of force development and speed strength

Why This Matters for Athletes

Whether you're a powerlifter trying to break through a plateau, a sprinter working on acceleration, or a strength athlete preparing for competition, the ability to generate force rapidly separates good performance from elite performance. Research from the National Strength and Conditioning Association has consistently shown that rate of force development is a critical factor in athletic performance across virtually all sports.

⚡ Quick Facts for Athletes

  • ✓ Powerlifters: Faster bar speed at 80-90% translates to higher max lifts
  • ✓ Track Athletes: Improved RFD enhances acceleration and sprint performance
  • ✓ Team Sports: Better change of direction and explosive movements
  • ✓ Recovery: 50-60% loads create minimal joint stress compared to 90%+ training
  • ✓ Training Frequency: Can be performed 2-3x weekly without excessive fatigue

Impact on Training Performance

  • Strength training: Teaches your nervous system to recruit motor units faster, improving your ability to accelerate heavy loads off the floor or chest
  • Power development: Targets the optimal zone of the force-velocity curve where power output (force × velocity) is maximized
  • Recovery: Lighter loads reduce systemic stress while maintaining high-quality training stimulus, allowing more frequent sessions

Why Use the Dynamic Effort Method?

1. Develops Rate of Force Development (RFD)

Dynamic effort work trains your nervous system to recruit motor units rapidly and generate force quickly. This translates to better acceleration in all movements—from breaking a heavy deadlift off the floor to exploding out of the hole in a squat.

2. Improves Bar Speed on Heavy Lifts

Powerlifters who incorporate speed work often report faster bar velocity on maximal attempts. When you're accustomed to moving weights explosively, heavy loads feel more responsive.

3. Enhances Athletic Performance

Speed strength is essential for sports requiring rapid force production: sprinting, jumping, throwing, striking, and change of direction movements.

4. Lower Injury Risk Than Max Effort Work

Training with 50-60% loads instead of 90-100% reduces joint stress and connective tissue strain while still providing valuable training stimulus.

5. High Training Volume Without Excessive Fatigue

You can perform 8-10 sets of speed work without the systemic fatigue of an equivalent number of maximal effort sets. This allows more frequent training and faster recovery.

6. Reinforces Optimal Technique

Lighter loads allow perfect form execution, ingraining proper movement patterns that carry over to heavier lifts.

The Science: Force-Velocity Relationship

The force-velocity curve demonstrates an inverse relationship: as load increases, velocity decreases. Dynamic effort training targets the middle-to-high velocity portion of this curve where power output (force × velocity) is maximized.

📊 What Research Shows

Scientists at McMaster University and the Australian Institute of Sport have demonstrated that athletes who train across multiple zones of the force-velocity spectrum—including dynamic effort work at 40-60% 1RM—develop more comprehensive explosive strength compared to those who only train heavy or only train light.

Practical takeaway: Combining maximal effort training (90%+), dynamic effort work (40-60%), and unloaded ballistics creates the most complete power development program.

Heavy Maximal Effort (90-100% 1RM)

High force, low velocity → Develops maximal strength

Dynamic Effort (40-60% 1RM)

Moderate force, high velocity → Develops power and RFD

Unloaded Ballistics (0-30% 1RM)

Low force, maximal velocity → Develops pure speed

By training across the entire force-velocity spectrum—including dynamic effort work—you develop comprehensive explosive strength.

Dynamic Effort Method Programming

Westside Barbell Template

The original dynamic effort protocol developed by Louie Simmons at Westside Barbell, studied and refined by strength coaches at institutions including Texas A&M University:

Dynamic Effort Lower Body (Squat Focus)

• Box Squats: 10-12 sets × 2 reps at 50-60% 1RM

• Rest: 45-60 seconds between sets

• Bands/Chains: Often added for accommodating resistance

• Total time: ~15-20 minutes of speed work

Dynamic Effort Lower Body (Deadlift Focus)

• Speed Deadlifts: 6-8 sets × 1 rep at 60-70% 1RM

• Rest: 45-60 seconds

• Variation: Sumo, conventional, deficit, or block pulls

Dynamic Effort Upper Body (Bench Press)

• Speed Bench: 8-9 sets × 3 reps at 45-55% 1RM

• Rest: 45-60 seconds

• Grip variation every 3 sets (close, medium, wide)

• Total: 24-27 reps in ~12-15 minutes

Load Selection Guidelines

  • Speed Squats: 50-60% of box squat 1RM (or 45-55% of competition squat 1RM)
  • Speed Deadlifts: 60-70% of 1RM (deadlifts require higher percentage due to no eccentric)
  • Speed Bench: 45-55% of 1RM
  • With bands/chains: Use lower bar weight (40-50%) since accommodating resistance adds load at lockout

Pro Tip: Bar Speed is the Metric That Matters

If bar speed slows down during your dynamic effort sets, the weight is too heavy or you're too fatigued. The goal is consistent, explosive velocity on every rep. If using velocity-based training tools, target 0.7-1.0 m/s for squats and 0.5-0.8 m/s for bench press during DE work. Without equipment, visually assess bar speed—if it looks slow, reduce weight by 5-10% or end the session. Track perceived bar speed in FitnessRec to monitor quality across sessions.

Accommodating Resistance: Bands and Chains

Westside Barbell frequently uses bands and chains with dynamic effort work to create accommodating resistance—resistance that increases as you move through the range of motion.

Bands

Effect: Provide increasing tension as you approach lockout, forcing continued acceleration

Benefits: Teaches explosive acceleration through full ROM, overloads lockout strength, prevents deceleration

Setup: Use 20-25% band tension at lockout (e.g., 50% bar weight + 25% band tension at top)

Chains

Effect: Add weight progressively as chains lift off the ground during ascent

Benefits: Similar to bands but more linear loading increase, easier to quantify

Setup: Use chains totaling 10-20% of 1RM, half on ground at bottom of lift

Straight Weight

When to use: Beginners, those without access to bands/chains, or when rotating training stimulus

Drawback: Natural deceleration occurs in final third of range as you "throw" the weight

Solution: Compensatory acceleration—consciously push/pull harder as bar gets lighter

How to Integrate Dynamic Effort into Your Training

Westside Conjugate Method

Four training days per week:

Sunday: Max Effort Lower (work to 1-3RM on squat/deadlift variation)

Tuesday: Max Effort Upper (work to 1-3RM on bench variation)

Thursday: Dynamic Effort Lower (speed squats and/or speed deadlifts)

Saturday: Dynamic Effort Upper (speed bench press)

Daily Undulating Periodization (DUP)

Rotate intensity zones throughout the week:

Monday: Heavy Squats 5×3 at 85%

Wednesday: Speed Squats 10×2 at 55%

Friday: Volume Squats 4×8 at 70%

Block Periodization

Dedicate specific training blocks to dynamic effort emphasis:

Block 1 (4-6 weeks): Strength accumulation, higher volume at 70-80%

Block 2 (3-4 weeks): Dynamic effort emphasis, 50-60% with speed focus

Block 3 (2-3 weeks): Competition peaking, 85-100%

Exercise Variations for Dynamic Effort Work

Lower Body

  • Box Squats: Westside staple, teaches explosive reversal and posterior chain drive
  • Free Squats: Better specificity for non-powerlifters
  • Front Squats: Speed work for Olympic lifters or quad emphasis
  • Speed Deadlifts: Conventional, sumo, deficit, or block variations
  • Trap Bar Speed Pulls: Lower technical demand, easier to accelerate

Upper Body

  • Bench Press: Competition grip, close grip, wide grip rotation
  • Floor Press: Reduced ROM, emphasizes lockout speed
  • Incline Bench: Shoulder-dominant variation
  • Push Press: Full-body explosive pressing
  • Speed Rows: Barbell or dumbbell explosive rows

Common Mistakes with Dynamic Effort Training

  • Using too much weight: If velocity drops, weight is too heavy. Ego has no place in speed work.
  • Insufficient intent: Going through the motions defeats the purpose. Every rep must be maximally explosive.
  • Too much rest: Resting 3-5 minutes between speed sets allows too much recovery. Keep rest to 45-75 seconds.
  • Too little rest: Under 30 seconds leads to excessive fatigue and velocity loss.
  • Wrong exercise selection: Complex movements with high technical demand (full Olympic lifts) are less suitable for DE method than simpler variants.
  • No variation: Rotating exercises every 2-3 weeks prevents accommodation and staleness.
  • Neglecting maximal strength: Dynamic effort enhances RFD but can't replace heavy training. You need both.

Warning: Speed Work is Still Hard Work

Don't confuse "lighter weight" with "easy training." Proper dynamic effort sessions are metabolically and neurologically demanding. The short rest intervals, high set count, and maximal intent create significant fatigue. If you're not breathing hard and sweating during speed squats, you're not pushing hard enough. However, if technique breaks down or bar speed slows significantly, end the session—quality trumps quantity in speed work.

Who Should Use Dynamic Effort Training?

Powerlifters

Benefit: Improves bar speed on competition lifts, develops RFD off the floor/chest, addresses weak points through variations

Implementation: 1-2 DE sessions per week using Westside template

Strength Athletes (Strongman, Weightlifting)

Benefit: Enhanced explosive strength for event-specific movements (log press, stone loading, Olympic lifts)

Implementation: 1-2 sessions weekly, often integrated with event training

Athletes (Team Sports, Track & Field)

Benefit: Develops speed strength crucial for sprinting, jumping, and contact situations without excessive muscle soreness

Implementation: In-season: 1-2 sessions; off-season: integrated with maximal strength phases

Advanced Lifters

Benefit: Provides variation stimulus, prevents accommodation to constant heavy loading, maintains speed qualities

Implementation: Periodized within training blocks or used in DUP framework

Less Ideal For:

  • True beginners: Need more time under tension and technical mastery before emphasizing speed
  • Pure bodybuilders: Hypertrophy requires higher volume at moderate intensity; speed work provides minimal muscle growth stimulus
  • Those lacking maximal strength base: Build strength foundation first (1.5× bodyweight squat minimum recommended)

Common Questions About Dynamic Effort Training

Do I need bands or chains for effective dynamic effort training?

No, bands and chains are excellent tools but not mandatory. Straight weight with proper explosive intent and compensatory acceleration (pushing harder as the bar gets lighter) works effectively. Start with straight weight to master the method, then add accommodating resistance for additional variation and stimulus.

How does dynamic effort training differ from explosive lifting like Olympic lifts?

Olympic lifts (snatch, clean & jerk) involve ballistic movements where you actually release the bar, requiring maximal velocity throughout. Dynamic effort uses controlled explosive lifts (squat, bench, deadlift) at submaximal loads. Both develop power but DE work has more direct carryover to powerlifting while being less technically demanding.

Can I build muscle with dynamic effort training?

Dynamic effort work provides minimal hypertrophy stimulus due to low time under tension and submaximal loads. Use DE for power development, then include traditional hypertrophy work (8-12 reps at 65-75% 1RM) as accessory movements if muscle growth is a goal.

How do I track dynamic effort training in FitnessRec?

In FitnessRec, log your speed work with detailed notes including percentage of 1RM used, perceived bar velocity (fast/moderate/slow), rest intervals, and whether you used bands or chains. Use the custom notes field to track bar speed quality across sessions—if you notice velocity declining over multiple weeks, reduce load or take a deload week. The app's percentage calculator automatically computes your DE loads based on your current 1RM.
