It may seem counterintuitive, but working opposing muscle groups at the same time can actually improve your results! Here’s a quick example: when doing a chest press, you are tightening the muscles in your back, imagine it like the hammer being cocked back on a gun. So, when you move to a back exercise next, your muscles are already set to work harder. That’s the ethos behind this workout from XHit Daily. It combines a back and chest workout to get you performing at the max while trimming inches off your torso and building strength. All you need for this routine is a light set of dumbbells and some serious energy!
