Does “exercise order” make a difference?
Walk into any gym and you will find those who swear you must do aerobic exercise and then weight training, those who say you should do weight training first and then aerobic exercise, and those who switch between both approaches to cover their bases.
A new study in the journal Applied Physiology, Nutrition, and Metabolism found that the order of exercises is not nearly as important as simply “performing weight training with a high intensity of effort” built in to your formula. It’s called Pre-Exhaustion or PreEx training and its premise is to exhaust muscles with specific isolation, single muscle exercises and then perform a compound exercise that involves that muscle plus surrounding muscles, so you get the biggest muscle-stimulation payoff.
So worry a bit less about exercise order, and more about exhausting each muscle group to its fullest potential. Make sure to include rest days for muscle recovery.
