No Need to Lift Super Heavy Weights to Build Muscle, Study Finds

Gaining strength is about how tough you work, not how most we lift.

If you’re looking to build muscle though worry about overdoing it with a barbells, here is some enlivening news: Research shows that contrary to renouned belief, lifting lighter weights for some-more reps can be only as effective as lifting heavier weights for fewer reps.

For a study, published in a Journal of Applied Physiology, researchers from McMaster University followed 49 young men over a march of a 12-week, full-body insurgency training program. About half a participants used lighter weights for sets trimming from 20 to 25 repetitions. (Each person’s weights were set during 30% to 50% of his one-repetition maximum, or the amount he could lift one time.) The other half lifted heavier weights (set during 75% to 90% of any man’s one-rep max) for sets trimming from 8 to 12 reps. Both groups worked until the indicate of fatigue.

What a researchers found: The gains in robust strength and distance among participants in a initial and second groups were not significantly different.

“This investigate is poignant since it hurdles stream insurgency practice convictions and guidelines,” says investigate author Robert W. Morton, a PhD claimant during McMaster University. “Put simply, your bid is some-more critical than a weight we use.”

Ideally, he says, a commentary will motivate some-more people to take adult resistance exercise, “particularly those who might have been intimidated by a need to sight with complicated weights,” he says. 

So go forward and squeeze whatever set of dumbbells we please—as prolonged as we keep adult a reps until you can’t do any more.
