The Claim

In healthy young adults performing low-intensity resistance exercise with blood-flow restriction at equal total training volume, occlusion pressures of 40% and 50% of arterial occlusion result in significantly lower ratings of perceived exertion and pain than occlusion pressures of 60% to 80% of arterial occlusion.

Source: Lower occlusion pressure during resistance exercise with blood-flow restriction promotes lower pain and perception of exercise compared to higher occlusion pressure when the total training volume is equalized.

In plain English

When doing low-intensity weight training with restricted blood flow, using 40% or 50% of the pressure needed to fully stop blood flow causes less perceived effort and pain than using 60% to 80% pressure, when the total amount of exercise is the same.

See the scientific wording

When performing low-intensity resistance exercise with blood-flow restriction at equal total training volume, occlusion pressures of 40% and 50% of arterial occlusion result in significantly lower ratings of perceived exertion and pain compared to pressures of 60% to 80% of arterial occlusion in healthy young adults.

Why this might work

When the cuff is looser, it presses less hard on the nerves and blood vessels in the limb, so fewer pain signals are sent to the brain and the muscles feel less tired during exercise.

  1. Study: Lower occlusion pressure during resistance exercise with blood-flow restriction promotes lower pain and perception of exercise compared to higher occlusion pressure when the total training volume is equalized.

    When people do light weightlifting with cuffs that squeeze their arms or legs, using looser cuffs (40-50% pressure) feels easier and hurts less than tighter cuffs (60-80%), even if they do the same amount of lifting. The study proves this.
