Similar Assertions

If you're a young guy lifting weights more often each week, you'll build more muscle and get stronger—but after a while, your strength stops improving fast, while your muscles keep growing a bit longer.

If you lift weights the same total amount each week, it doesn’t really matter whether you do it in one big session or spread it out over several days—your muscles will grow about the same either way.
