Should I do upper and lower body strength training in separate workout sessions?
There’s no need to choose between legs/glutes and arms/back on a single strength day; you can incorporate all muscle groups into your routine without risking injury, as long as you don’t overdo the amount of weight/resistance or the number of sets and reps. In fact, full body workouts are a great use of limited time, since you’ll get in the maximum amount of muscle-building. Just be sure to take time — about one to two days — between workouts to allow your muscles time to recover. If you would prefer to focus on one area of the body (either lower or upper body), remember to switch the next time you strength train.
