15 of the Best Leg Exercises for Muscle Size and Strength

15 of the Best Leg Exercises for Muscle Size and Strength

The muscles of your thighs and hips are some of the largest in your body. That means leg workouts not only burn a ton of energy, but they also require producing that energy as quickly as possible to keep those legs going.

So, if you want great legs, you’re going to have to earn ’em.

There’s good news, though: You don’t have to cram all of your lower-body exercises into a single, scorching leg day workout each week.

“In fact, if you only work your legs once a week, you’ll be shortchanging your results,” says Trevor Thieme, C.S.C.S.

That’s because muscle protein synthesis (a.k.a. muscle growth) lasts for up to 48 hours after a strength-training session.

“So if you work your legs at least a couple of times a week — with adequate rest between those workouts — you can potentially keep your muscles in a constant state of adaptation.”

Adaptation equals growth and greater strength. Maximize both by adding two to three exercises from the list below — all pulled from BODi’s extensive collection of expert-designed programs — to your leg workouts a few times a week.

But keep in mind that if you’re already doing a BODi program, your legs are probably getting plenty of work already.

Don’t be afraid to mix and match, picking different moves or combination of moves each time and exercises that target different muscle groups.

1. Jump Squat

Appears in: 22 Minute Hard Corps – Resistance 2

Benefits: This move works almost every muscle in the lower body — quads, glutes, hamstrings, and calves — while also improving core stability and hip and ankle mobility.

  • Stand with your feet hip-width apart, toes pointed forward, holding a dumbbell or sandbag in both hands in front of your chest.
  • Keeping your back flat and chest up, bend your knees and push your hips back until your thighs are parallel to the floor.
  • Explode upward, jumping as high as you can.
  • Land softly, immediately dropping back down into a squat to begin your next rep.

2. Romanian Deadlift

Appears in: LIIFT MORE – Week 1/Day 4: Hamstrings & Glutes

Benefits: Nailing the RDL takes practice and precision to avoid common mistakes in form, but the benefits to glutes, hamstrings, and lower back muscles are well worth the work.

  • Stand with your feet shoulder-width apart and parallel, holding a pair of dumbbells in front of your thighs, palms facing you.
  • Draw your shoulders back, unlock your knees, and engage your core as you slowly hinge at your hips, sending your hips back.
  • Maintaining your lower back’s natural arch, lower the weights until your torso is nearly parallel to the floor. Keep your head neutral and the weights close to your body throughout the movement.
  • When you can’t descend farther without rounding your back (you should feel a deep stretch in your hamstrings), pause, and push your hips forward to return to the starting position.

3. Standing Hip Extension

Appears in: 21 Day Fix – Barre Legs (as the Attitude)

Benefits: As you balance on one foot, this move strengthens your glutes and hamstrings while improving posture and core stability.

  • Stand tall, hands on your hips, with your heels together and your toes turned out slightly.
  • Move your right foot back, lightly touching the floor behind you with your big toe and letting your heel drop slightly inward. This is your starting position.
  • Keeping your torso tall, lift your right leg behind you as high as you can, squeezing your right glute.
  • Return to the starting position, gently tapping the toes of your right foot to the floor, and repeat.
  • Do equal reps on both sides.

  • Keeping your chest up, shoulders back, core engaged, and back flat, take a large step forward with your right foot.
  • Lower your body until your front thigh is parallel to the ground and your rear knee is bent about 90 degrees (it should hover a couple of inches above the floor).
  • Pause, and then push off your front feet from the heel to reverse the movement and return to the starting position. Repeat, this time stepping forward with your left foot. Continue alternating legs with each rep.

5. Step Up Convicts

Appears in: P90X2 – P.A.P. Lower

Leg Muscle Anatomy

The lower body is an anatomy student’s nightmare. Full of oddly named muscles like the gracilis and the sartorius, the legs can look like an indistinguishable hodgepodge of tissue to the uninitiated.

Boiling leg anatomy down to the basics, the biggest players are the quadricepshamstrings, adductors, and calf musclesHere’s how those heavy hitters help you strut your stuff:

Quadriceps

quad muscles | thigh anatomy | leg workouts

Your quads are comprised of four individual muscles on the front of your thighs. Their main job is to extend your knee — which makes them essential in movements like running, jumping, and kicking. In the gym, your quads light up whenever you squat, lunge, or step upward.

Hamstrings

hamstring muscle anatomy | leg workouts

These muscles on the back of your thighs — the biceps femoris, semitendinosus, and semimembranosus — flex your knee, helping you curl your heel toward your butt. They also help with the rotation of your lower leg and assist your glutes in extending your hips to move your thigh backward.

Calf Muscles

calf muscles | leg workouts

Two muscles in your lower legs are responsible for pointing your foot (extending it downward). The gastrocnemius is on top, closer to the back of your knee, and it points your foot when your leg is straight; the soleus lies beneath it and points your foot when your knee is bent.

Another muscle, the tibialis anterior, lies alongside your shin in the front of your lower leg, and it’s responsible for flexing your foot (pulling the toes up toward the shins).

Adductors

leg workouts | abductors adductors

This set of about a half-dozen muscles on your inner thighs — the most powerful of which are the longus, magnus, and brevis — are responsible for pulling your thighs together and providing stability during big-ticket moves like squats, lunges, and sprints.

What about the glutes?

glute muscle anatomy | leg workouts

Colloquially, your butt; technically, the gluteus maximus, medius, and minimus. The glutes aren’t actually part of your legs — they are part of your hip.

Nevertheless, they’re responsible for some of your lower body’s most fundamental movements. Primarily, they extend the hips (a critical part of rising out of a squat or a seated position), move the legs away from the body, and rotate the legs outward.

As you can see, keeping up with your legs’ demands as you push the limits of their strength and stamina will leave your heart pounding, your lungs heaving, and your body’s sprinkler system in high gear — as long as you do it correctly.

Is it any wonder that so many people skip leg day?
