How does Machvise even hit anyone?
Changing his weight at will implies being able to lower it to close to nothing too. That is probably the technique he uses to reach dozens of meters in a single jump before increasing it greatly again to fall back with mighty power.

While falling, he could also lower his weight again to the weight of a feather and use the large surface of his body to glide sideways to reach any fleeing enemy. This is what a falcon in free fall does, precisely reaching his moving target with the fine tuning of his wings.

Using this, he can reach great velocities he would otherwise never reach with his legs only, running after his opponent in a more "traditional" wrestling style.
