Go straight to the mixed reality training feature. The focus mitts use a standard 1-10 punching system that all the boxing coaches I have trained under has used. The heavy bag satisfies the continuous punching need that will burn the most calories. If you looking for some quality practice while away from the gym or need to learn your 1-10 punches fast this will definitely help. Some glaring differences I see is there’s no slipping the punch just ducking, the combination are random every time where I am used to drilling the same 3-4 combinations in a session, and the coach calls out the combination every time while I’m used to a few random jabs to test my guard the the pads are flashed to start the combo. All in all you can tell the developers went to a boxing gym.
