To gain health benefits, muscle-strengthening activities need to be done to the point where it's hard for you to do another repetition without help. A repetition is one complete movement of an activity, like lifting a weight or doing a sit-up. Try to do 8—12 repetitions per activity that count as 1 set. Try to do at least 1 set of muscle-strengthening activities, but to gain even more benefits, do 2 or 3 sets.
You can do activities that strengthen your muscles on the same or different days that you do aerobic activity, whatever works best. Just keep in mind that muscle-strengthening activities don't count toward your aerobic activity total.
There are many ways you can strengthen your muscles, whether it's at home or the gym. You may want to try the following:
- Lifting weights
- Working with resistance bands
- Doing exercises that use your body weight for resistance (i.e., push-ups, sit ups)
- Heavy gardening (i.e., digging, shoveling)
