Can you do jumping Jack's, jump squats and jump around in hitt classes. I really enjoy hitt but at 10 weeks with my first Im paranoid and read such different things. Some say no to jumping but then running seems OK, surely when you run your bouncing too. I do feel super tired after a 30 min hitt atm but I still enjoy it. But are there risks I should be aware of. I keep going back and forth.
