Speed Work Guide 2026: Dynamic Effort Training Explained
Moving a submaximal weight fast is not "easy day" — it is a distinct training quality. Done right, speed work builds the rate of force development that heavy singles cannot.

What Dynamic Effort Actually Trains
Max-effort lifting grinds at ~85%+ of 1RM and develops absolute strength. Speed work lifts 50-75% as fast as possible, targeting rate of force development — the ability to produce force quickly. Both matter in a meet: the absolute ceiling sets what is possible; RFD decides how fast you get there and whether a slow-grinding third attempt actually locks out. Westside formalized this as Dynamic Effort day; modern conjugate and concurrent programs still build around it.
Speed Work by Lift
| Lift | Typical % | Sets/Reps | Accommodating resistance |
|---|---|---|---|
| Squat | 50-60% | 10-12 x 2 | Bands or chains 25-30% |
| Bench | 40-50% | 8-9 x 3 | Bands/chains 20-25% |
| Deadlift | 50-70% | 6-10 x 1-2 | Chains more common |
| Press (if used) | 50-65% | 6-8 x 3 | Rare — press is already fast |
Speed Work Done Right
- •Bar speed is the metric — if it is not fast, the weight is too heavy
- •Rest 45-60 seconds — this is not conditioning, it is neural work
- •Compensatory acceleration: push the bar as hard as a max, even at 60%
- •Bands/chains rise through the lift — teaches acceleration into lockout
- •Speed work is a skill — treat the light weight like a competition attempt
The Skeptic's Case
Some modern coaches (Bryan Mann, Mike Tuchscherer camps) argue speed work is overrated for raw powerlifters — that velocity-specific adaptations are real but small, and that submaximal work at high RPE builds more practical strength. The truth is probably lift-dependent: speed squats and speed deadlifts have clearer carryover than speed bench. If your grinding problem is "I am slow off the floor," speed pulls help. If it is "I am just weak," speed work will not fix it.

Frequently Asked Questions
What is dynamic effort training?
Lifting submaximal weights (40-75% 1RM) as fast as possible to train rate of force development — the speed of force production, not its ceiling. Popularized by Westside as "speed day."
Does speed work build strength?
Indirectly — it builds the ability to produce force quickly, which helps you break through sticking points and makes heavy attempts feel faster. It does not replace max effort work.
What percentage should speed work use?
Roughly 50-60% for squat, 40-50% for bench, 50-70% for deadlift — plus accommodating resistance. The bar must move fast; if it grinds, the weight is too heavy.
Do I need bands for speed work?
No — straight-weight speed work still works. Bands and chains make the weight heavier at the top, teaching acceleration, but they are an enhancement, not a requirement.
How many sets of speed squats?
Westside classic is 10-12 sets of 2 reps with short rest. The point is many fast, fresh reps — not fatigue.
