Why do guys get faster results at the gym?

[Anonymous]

I have to work to stay fit and in good shape, but my boyfriend can quit the gym for several months, lose his abs, and visible muscle...but when he goes back he can have it back in no time at all (seems like a couple weeks?). Why is this? I've noticed that a lot of guys have that ability?

They're actually right, it's because guys have a higher quantity of testosterone, naturally. That doesn't mean you should have testosterone injections though: it is the substance that forces the body to form into a 'male' phenotype.

The difference between testosterone and oestrogen, in short.

its because most of our body fat are here due to hormone oestrogen (which gives to us our secondary sexual characteristics=our curves)

Testosterone is a hell of a drug.
