Velocity loss guidelines — the threshold to use for every training goal

Every velocity-loss decision comes down to one trade: how much fatigue you’re willing to buy for the adaptation you want. This table is that trade priced out. Pick the goal, read the cutoff, program the set.

How to read this chart

Three columns. Velocity loss is the cutoff — the percentage drop from the fastest rep of the set to the rep that ends it. Set strain is what that cutoff costs you in fatigue. Best for is the adaptation the band actually buys.

The bands are not a ladder to climb. Higher isn’t more advanced, it’s just more expensive. A 30 % band in a hypertrophy block and a 10 % band in a peaking week are both correct programming; running 30 % year-round is not.

Note the upper-body qualifier on the bottom row. Failure sits at roughly 40 % velocity loss on squats and deadlifts but 45–50 % on bench and rows — upper-body lifts tolerate a deeper drop before the bar stops moving. A 40 % cutoff on bench is a hard set; a 40 % cutoff on squat is a failed one.

Using the bands

• 5–15 % — power, peaking, in-season. Keeps bar speed high and volume low. This is the taper band: hold intensity, cut reps, let supercompensation surface.
• 20–25 % — strength and hypertrophy. Enough stimulus to force adaptation, little enough fatigue to repeat the session in 48 hours. If you only ever program one number, program this one.
• 30 % — hypertrophy, intense strength. More total reps and more accumulated fatigue, which suits a block where volume is the driver and recovery is planned for. Also useful as a one-off with an athlete you suspect is sandbagging — give them 30 % and let the rep count tell the truth.
• 40 % (45–50 % upper body) — rare, deliberate use only. This is training to failure with a number attached. Occasionally worth it to test a limit or finish a block; ruinous as a habit.

Pitfalls

• Thresholds assume maximal intent on every rep. A lifter pacing themselves will drift toward the cutoff slowly and rack the bar having done nothing hard. The number only measures fatigue if every rep was a genuine attempt at maximum speed.
• Low-rep heavy sets break the resolution. On sets of 1–3, velocity loss jumps in coarse steps — 15 % on rep 2, 35 % on rep 3, no useful reading in between. Use RPE in-set and read velocity loss after.
• Readiness distorts the reading. On a bad day the first rep is already slow, so a “20 %” set is deeper into real fatigue than the number suggests. See the velocity-loss set chart for what a suppressed first rep does to the reading.
