That’s what you call training hard

The rewards of lifting weights are more strength, bigger muscles, and a fitter, toned body. But to achieve that, many know that lifting weights is not easy. It’s actually quite challenging. The most important thing to get results is that training is always a challenge.

This guy seems to have reached that point and is fighting so hard that even his head is developing muscle.
