When young men lift weights for 12 weeks, a small spike in a hormone called GH right after working out is slightly linked to their muscle fibers getting bigger — even though we don’t think GH directly makes muscles grow.

Associations of exercise-induced hormone profiles and gains in strength and hypertrophy in a large cohort after weight training

Cohort Study

Human

2012 Jul

This study found that in young men doing weight training, bigger spikes in a hormone called GH right after workouts were slightly linked to bigger muscle fibers growing over time — even though GH doesn’t directly make muscles grow. This matches what the claim says.

Similar Assertions

Even if your muscles get a big burst of growth hormone right after lifting weights, that doesn’t mean you’ll grow bigger muscles over time—some people who got way more of this hormone didn’t grow more muscle than others.

Even if your growth hormone spikes right after lifting weights, that doesn’t mean you’ll end up with bigger arms after 8 weeks of training.

Even if your testosterone, growth hormone, and IGF-1 levels spike after a workout, that doesn’t mean you’ll grow more muscle over time—those hormone spikes don’t seem to explain why some guys get bigger than others after 16 weeks of lifting weights.

After working out with weights, the levels of certain hormones in the blood don’t predict whether a guy will gain more or less muscle over 16 weeks — so those hormones probably aren’t the main reason some people grow bigger muscles than others.

Even if your body releases a lot more of the 'muscle-building' hormones after a workout, it doesn’t mean you’ll grow more muscle than someone whose hormone levels stay low—studies show both groups end up with the same muscle size.
