How it works

Lifting faster makes your muscles need energy quicker, so your body uses more oxygen to keep making energy. This lets you do more reps without getting more tired from burning sugar without oxygen, so you lift more total weight in the same amount of time.

Most probable mechanism

In Simple Terms

When you lift weights as fast as you can, your muscles need energy more quickly. Your body responds by using more oxygen to make energy, which lets you keep going for more reps without getting as tired from burning sugar without oxygen. This lets you lift more total weight in the same amount of time.

Causal chain
1

Maximal concentric velocity increases the rate of muscle contraction and power output, raising immediate energy demand per unit time.

which leads to
2

The increased power output and repetition rate elevate ATP demand beyond the capacity of immediate anaerobic stores, requiring faster oxygen delivery to mitochondria.

which leads to
3

Increased oxygen delivery and utilization shift the relative energy contribution from anaerobic to aerobic metabolism, sustaining ATP production without accumulating fatigue-inducing metabolites.

which leads to
4

Sustained aerobic ATP production allows more repetitions to be completed before fatigue limits performance, increasing total volume load without increasing time under tension.

Science Topic

Does velocity-based training increase volume load more than tempo-based training during bench press?

Supported
Velocity-Based Training

We analyzed one assertion on this question and found that velocity-based training may allow for more total weight lifted during bench press compared to tempo-based training. In a single set at 70% of maximum strength, using real-time feedback to maintain faster lifting speed led to about 12% more total weight moved, even when the time muscles spent under tension stayed the same [1]. This suggests that controlling speed by aiming for faster movement — rather than sticking to a fixed rhythm — might let people complete more repetitions before fatigue sets in, increasing the overall mechanical work done. We did not find any evidence contradicting this observation. However, this finding comes from just one scenario: one exercise, one intensity level, and one type of feedback. We don’t yet know if this pattern holds across different weights, training volumes, or populations. It also doesn’t tell us whether this increase in volume load translates to greater long-term muscle growth or strength gains. What we’ve found so far leans toward the idea that velocity-based control can increase the total load lifted in a single bench press set, simply by enabling more reps without changing how long the muscles are working. For someone looking to lift more weight in a session, this could mean using a device or app that shows bar speed in real time — helping them push harder without overextending. But whether this approach is better overall remains unclear based on the limited evidence we’ve reviewed.
