We will do this with supination to call one of the main functions of the biceps, but that's not the only twist. The dumbbell must sit in an offset weight distribution in the hand, which means that you do not grasp the dumbbell in the middle of the handle, but that the thumb rests on the weight plate.
In this way, when you supinate the short head has to work slightly more against the offset resistance. (Due to the supination, the short head of the biceps becomes slightly harder than the long head.) The development of the short head will make the bicep look thicker from the front.)
The intensity technique we are going to use. 39; drop sets, and my preference here is crazy 8s. This is 8 repetitions to failure, 8 repetitions to failure with a lighter dumbbell and another 8 repetitions to failure with an even lighter dumbbell. Let rest for 2-3 minutes and make 1
