Here’s why – Your upper arm is made up of two major muscle groups — the biceps and the triceps, and many lifters make the mistake of only training the biceps, failing to realise that the triceps only make up two-thirds of the upper arm mass. The triceps are a beautifully-shaped muscle when well developed. Surprised?
I’ve had friends who want bigger arms but only ask me what the best biceps exercises are. I normally end up giving them my favourite triceps exercises instead.
For good arm development, allocate a few more sets for your triceps rather than biceps. If you always start your arm training with your biceps first (almost everyone I see in the gym does this), try switching the order. Train your triceps first before you train your biceps.
Though you should always strive for a balance of all muscle groups, trust me when I say that if your biceps development are weaker but if you possess well developed triceps – your arms would still look spectacular! The same can’t be said for the reverse.
The bottomline? If you want big arms, get big triceps!
