Adults should engage in weight training at least two times a week, recommends the Centers for Disease Control and Prevention. You can always increase the number of days you train with weights as long as you give each muscle group three days of rest before training it again. Opting to increase this to three or four days will help you to reach your goals more quickly, as you will burn more fat and calories.
Your form might start to give just a little or you cant quite get to the rep range,â Booker says. If your muscles fail or you canât maintain form before reaching 14 reps, pick a set of weights five pounds lighter. If you can easily do more than 22 reps, pick a set five pounds heavier. This determines your lighter set of weights. Add 10 pounds, and thatâs how much you should be lifting when reaching for a heavier set of weights.
