Weight / Fat loss

I've been doing leg presses and calf raises (mainly because I can't face taking 200kg off the bar in front of everyone once the giants have finished). I heard that working on larger muscle groups (quads and glutes) causes your body to produce higher levels of testosterone, helping the rest of the workout. Is this BS?

If it is BS, its BS I follow.

The idea is to shock Your body into producing muscle building Chemicals/hormones etc.

I start each workout. With these..

Deadlift to hips, push striaght legs, snatch to shoulders, push up till arms straight, reverse, and repeat. (I Guess theres a name somewhat Shorter than that). It uses a shit load of muscle fibre, and thus has the best chance of switching the body to muscle building mode. Its also an awesome rugby forward routine.

Exactly why I do this when I'm rarely playing rugby, and InFact preparing for a season of cycling up Mountains. Is a Beyond me.

BTW. This is all nicked from a PM on here. From TM.
