In this article we'll take a close look at vertical chest press.

MUSCLES TARGETED: pectoralis major

STARTING POSITION

Sit down and lean back. Grasp handles with a closed, pronated grip. Align handles with nipples. Push handles away from chest to a fully extended elbow position. This is starting point for all repetitions.

BACKWARD MOVEMENT

Allow handles to slowly move backward until level with chest.

FORWARD MOVEMENT

Push handles away from chest to starting position. Do not arch back or lock elbows. Repeat or finish set.

2. It takes a dose of at least 300 milligrams of testosterone to raise body's level above normal.

3. It acts directly on muscle itself.

4. It stimulates release of growth hormone.

5. It has an anti-catabolic effect.

From these facts we can deduce that testosterone is an effective aid to muscle building and that it must be taken in significant quantities to have this effect. As far as bodybuilding is concerned science beyond this is somewhat limited as most users base their steroid regimes on little more than trial and error or advice of 'veterans'. Due to illegal nature of steroid use little scientific data exists to confirm effectiveness of many steroid supplements in use.

It is perhaps tendency of some bodybuilders to use a combination of powerful steroids and other drugs that presents very real dangers that have sometimes led to tragic conquences.
