Here we go with day two! If you’re feeling a little soreness from yesterday’s workout, that’s great! We’re going to focus on our back and arms today, letting the muscles we worked yesterday rest and recover. A strong back will help give you great posture, prevent injury, and keep your body in balance. You don’t want to overlook training any muscle group for this reason. Today we will be keeping our rest phases shorter than yesterday, which will get that heart rate up and have you sweating.
