Fact or Fiction
To build strength, lift heavier weights. Fiction. As long as you do enough reps, nearly all weights yield the same strengthening results. In other words, curling a 15-pound dumbbell 20 times can build as much muscle as curling a 50-pounder five times. The key is working to fatigue, regardless of how you get there. If you hit the gym to stay strong and healthy, you can lift lighter weights to fatigue and still gain strength. That goes for body-weight moves like push-ups and pull-ups, too. You can make these exercises just as effective as barbell work – just make sure to keep going until you max out.
