Weight training of one arm benefits both arms

It's time to go to the gym to do some weight training of the arms today. Unfortunately, the brutal weekend makes your left arm not moving for some time. Not to worry—new research shows that doing some bicep curling training with your right arm can benefit both of your arms.
A new study conducted by researchers from Chilean, French and Australian institutes found that if you do one-sided arm resistance training for one month, especially eccentric training, the other arm with less activity will maintain more muscle mass and even increase strength.
Any bodybuilding sportsman will say that when you lift dumbbells, your muscles work through teamwork to complete the action, support and fix various bones. Thus, don’t be surprised, parts of the body that are not obviously involved in one action may actually be involved.

When it comes to contralateral limbs like our arms, few studies specifically test this assumption. Neither of the two studies that tested significant effects discerned whether the type of training had an effect.
However, the specific types of weight training are not trivial.
Lift the dumbbells and bend your elbows to bring the dumbbells closer to your shoulders – this action is done through the concentric contraction of the biceps, the muscle fibers contract and the entire biceps muscle becomes shorter.
