Like we said, lifting six reps or less with as much weight as possible is great for improving strength. But you only want to go really big while doing compound lifts —squats, deadlifts, lunges, and Olympic lifts like cleans —that involve multiple muscles and joints, says Suter. Because, when you perform these compound movements, the force is spread out between so many muscles, connective tissues, and joint structures that everything gets worked just the right amount.
Nothing gets overstressed, she says. But if you try to curl your one-rep max, you run the risk of injuring your biceps and your elbow joints—either all at once or over time, explains Sam Simpson, C. The same goes for other isolation exercises like calf raises, glute kickbacks, and triceps extensions.
So once you work up to it, go ahead, lift really heavy loads six reps or fewer —but only when performing sturdy, compound lifts. With anything else, cap the weight at something that you can handle for eight reps at a time. Perform six to eight reps per set and you'll need 60 to 90 seconds of chill time before going again, he says.
Some lifters like to achieve that by lifting really heavy for a few weeks, then giving themselves a light week for recovery. Simply stated: Strength training can improve your ability to learn and think as you age.
Resistance training using body weight and with free weights, strengthens more than just your muscles. It also strengthens your bones and connective tissues. This added strength and stability will help you ward off injuries and keep a strong body.
It can also help reduce symptoms of many conditions like back pain , arthritis, fibromyalgia , and chronic pain.
It seems counterintuitive, but strength training has been shown to improve endurance , speed, and running economy the amount of energy and effort it takes to do something like run a five-minute mile. A recent study showed that lifting heavier weights improves economy more than lighter weights. That extra weight on the bar will pay off during your next run or spin class. Inactive adults can lose 3 to 8 percent of muscle mass per decade. You might lament the loss of your rock-hard arms or killer abs, but even worse, muscle weakness is linked with an increased likelihood of death in men.
Heavy resistance training can help fight, and reverse, the loss of muscle mass. It can also strengthen bones and help prevent osteoporosis , especially in postmenopausal women.

Or, get stronger at any of your lifts with the Smolov program , a week long guide to improving your squats of all types, and gain strength. All it takes is one lift to get started!
Follow these tips to stay safe in the gym:. This article explains whether weight…. Exercise is an important lifestyle habit that can help you manage your blood sugar levels if you live with type 2 diabetes. For the heavy lifters, it took less reps to do so; for the light lifters, more reps. You can read more about the results of that study here on 24Life. At the end of the study, all the participants had gained muscle strength and size — in fact their gains were almost identical.
The key to gains was total muscle fatigue, not at all dependent on weight. What happens to your body: High reps increase your heart rate and produce a cardio effect to help burn calories and fat. High reps build muscle endurance, which supports muscles while working under stress. McCall adds that high reps create a metabolic demand on the muscle that depletes glycogen stores in the muscle.
A result of high-rep training is the body may start storing more glycogen, increasing muscle size. What happens to your body: Heavy weights at low reps break down muscle fibers, and the body builds muscle and increases muscle mass by repairing these fibers. Increased muscle mass elevates metabolism, which helps your body continue to burn calories long after your workout.
Heavy lifting also strengthens bone density, which can reduce the risk of breaks and fractures as you age. If you lift heavy, you test your mental strength as well. So whether you are doing five dumbbell curls with a pound weight, or 20 reps with a 5-pound weight, as long as you are getting to the point of muscle fatigue, you'll get stronger.

A study found that a group of men who lifted heavy weights to the point of "failure" or muscle fatigue gained the same amount of muscle and improved their strength as much as the other group that lifted lighter weights for more reps. This study in found those same results. Some workouts that you might do that use light weights include a barre class, yoga sculpt, Pilates, or "sculpting" classes. Or a light-weight workout may look like doing bicep curls with a lighter weight like say pounds until you can't lift any more with good form.
On the other end of the spectrum is doing squats with an Olympic barbell, which will fatigue your muscles after only a few reps. What are some reasons you may choose to lift light weights over heavy? If you're new to working out or starting a new fitness program, light weights may be a good choice. Then once they get the form down and feel comfortable, they can increase the resistance," says fitness trainer Heather Marr.
Other things you can consider are that light weights are a good option for reducing the risk of injury -- you're just less likely to hurt yourself using a 5-pound weight over say, a pound weight. You can also bring light weights into other types of workouts to add more resistance and keep your heart rate up.
For example, in some of my dance cardio classes we do dance routines while also holding a 2- or 3-pound weight, which adds resistance my arms are always burning by the end and makes the cardio workout harder.
