This Is How Much Weight You Need on the Leg Press for Stronger Legs

Whether you're looking to save your back from barbell-induced discomfort or just want to try some new exercise equipment, the leg press is a great tool that you can most likely try at your gym.

But if you're new to this machine, you probably want to know the average weight for leg press exercises. Read on to learn more about your ideal leg press weight, how to program your reps and the best foot alignment for your goals.

If you're wondering, "How much should I leg press?" there's no easy answer. As with most types of weight-lifting, there's no single average weight for the leg press. The amount you can press depends on your age and fitness level. Those who frequently strength train may be able to leg press well over 100 pounds, whereas others may be challenged by pressing the machine alone.

Before you start throwing weight on the machine, figure out the average leg press weight to start with. If you've never used the machine before, start with about 50 percent of what you imagine you'd be capable of pressing, says Sam Becourtney, DPT, a physical therapist at Bespoke Treatments in New York City.

More specifically, beginners should start with a weight that's about 50 to 75 percent of their body weight, regardless of your sex and then build up from there, Becourtney says. Always take the weight of the machine into consideration and test a few weight-less presses before adding plates.

Keep in mind: There's no such thing as a good or bad leg press record weight. For many beginners, leg pressing 100 pounds is an excellent achievement. For more experienced lifters, a 500-pound leg press may be considered ideal. The goal is progress, after all.

As you grow more comfortable and experienced with the exercise, you can add more weight to the machine. Advanced lifters can usually lift up to four or five times their body weight, Becourtney says.

Playing with your foot placement is another way you can progress the leg press machine, according to Carolina Araujo, CPT, a California-based strength coach. For instance, a high and wide foot placement can help you target more of your glute muscles. A narrow stance focuses in on your quads.

Before you get your lower body working, though, you want to make sure your leg press form is correct. As with all new forms of lifting, it's best to test a few reps or sets without any weight at all. This step is especially important with the leg press, as different machines have different weight and function slightly differently.

There are a few different types of leg press machines your gym may have. The seated leg press machine is one of the most common, which has a totally horizontal seat, Becourtney says. You may also see a 45-degree or vertical leg press, which has you pushing upward at a diagonal angle.

You may even come across a lying leg press, where you lie flat on your back and push the press horizontally. Though that's generally used in a physical therapy setting. And although different leg presses may have you push the weight at varied angles, they generally work the same and use the same form.

Regularly using the leg press is a great way to improve your leg strength. But the way you program your sets and reps determines whether you focus on muscular size or endurance.

Generally, the amount of weight you're pressing should be inversely related to the amount of sets you perform, according to the American Council on Exercise (ACE). If you're a beginner and pressing about 50 percent of your body weight, aim for about 10 to 12 reps at the start, Becourtney says.

Then, once this weight and rep range starts to feel comfortable, you can increase your weight gradually, adding small increments of weight each set or workout, depending on your comfort level. You want to increase toward a weight that's challenging but doesn't cause you to break down in form (this helps you avoid injuries).

"You should be able to do complete the final 'working set' and only have 1 to 2 repetitions in reserve, meaning you were close to your maximum effort but did not reach a point of [form breakdown] where injury may be a risk," Becourtney says.

As you get stronger, you can increase your weight or reps depending on your goals. If you're looking to build muscular endurance (which is especially helpful if you play a sport), you can increase your reps gradually up to 30, according to the ACE.

Or, if you're training for hypertrophy (increased muscle size), you can keep your total reps low (at most 6 reps) and increase your weight more quickly.
