Steady Weight Lifting Increases Stregnth

A study published in the Scandinavian Journal of Medicine & Science in Sports observed two groups of weight trainers: One group exercised five days a week, and the other crammed their workout into one day.

The two groups performed bicep curls. Those who exercised more frequently saw a 10% increase in muscle strength over four weeks. Those who exercised once a week did not see gains in strength, but did develop thicker muscles.

This means if you miss several weeks of exercising, cramming more lifting into one workout would not “make up” for it. Researchers also want to remind gym-goers that rest days are just as important. “If someone was able to somehow train 24 hours a day, there would actually be no improvement at all,” Professor Ken Nosaka said.
