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.

Effects of rest intervals and training loads on metabolic stress and muscle hypertrophy

Randomized Controlled Trial

Human

2018 Mar

Even though one group had a big spike in a growth hormone after working out, both groups ended up with bigger arms after 8 weeks — and the size of the hormone spike didn’t predict who got bigger. So the hormone spike doesn’t seem to matter for muscle growth.

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 though lifting weights with short breaks makes your body release more growth hormone, that doesn’t mean you’ll grow bigger muscles over time.

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 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.

Just because your testosterone, growth hormone, and IGF-1 levels spike after a workout doesn't mean those spikes are what make your muscles grow.
