Do 1-3 days of strength training. The counterpart to regular aerobic exercise is strength training or resistance exercise. These activities help build and support lean muscle mass in addition to providing other health benefits.[28]
Regular strength training has many benefits outside of building stronger muscles. Regular weight bearing exercise helps decrease your risk of osteoporosis by making your bones stronger and denser.[29]
Experts recommend doing about 2 days of strength training each week. It's important to work every major muscle group including: arms, chest, back, core and legs. Lift free weights, use weight machines or do weight bearing activities like yoga or pilates.
Separate each strength training day by at least one day of rest to all your muscles to recover and repair efficiently.[30]
