When strength training, whether using weights, machines, resistance bands, or no equipment at all , it’s common practice to work both arms or legs at the same. So next time you do your routine, try working all your reps on one arm or leg at a time. In some exercises when you move both arms or legs together, you can cheat by letting

your dominant side do the brunt of the work, so this technique allows you to concentrate on strengthening both sides equally. This workout may take you twice as long, but your heart will keep pumping through your entire workout, which means you’ll actually burn more calories overall.
