"When you're training, do something that's going to invigorate the whole entire body," Peter says, explaining this approach is better than just focusing on 1 muscle group.
Peter demonstrates how to incorporate 3 moves (a curl, squat and a press) into one move and says slowing down the move will help you to get more out of it. And for beginners, he suggests using no weights or small weights when starting.
The celebrity personal trainer says the best approach to achieving a fitness goal, like weight loss, is to do it with a true expression of what you enjoy, for instance, dance, martial arts or weight training.
"Put your whole essence into it, whatever it is you're going to do. Don't go halfway, go all the way," he says.
