If you want big, strong, tough quads, then you need to introduce them to stimuli beyond what they’re already used to. That means adding tough quad exercises to your leg workouts.
Formed by four large muscles on the fronts of your thighs, the quadriceps straighten your knees (such as when you stand up from a seated position), and prevent them from buckling (such as when you land after striding, stepping, or jumping).
Over the course of an average day, your quads might help you scale several flights of stairs, carry you across miles of city blocks, and push you up from a chair dozens of times. Throw exercise into the equation, and they become even more central; squatting, lunging, running, jumping, and virtually every form of locomotion all require tremendous strength, power, and endurance in the quads.
“Since the quads are a large muscle group that can exhaust quickly, you can expect Bambi legs after a tough leg day,” says Braun. While we can’t make quad training easy, we can help make it effective.
9 of the Best Quad Exercises
Below are some of the most quad-searing moves available in Beachbody On Demand‘s rapidly growing library of muscle-building, fat-burning, professionally-designed workout programs. Some of these quad exercises require basic equipment such as a bench or a pair of dumbbells, but many require nothing more than your body weight, a few square feet of space, and a megaton of mental toughness.
Pick two or three moves from the list below any time you want a kick in the quads, or as a supplement to any Beachbody On Demand program you’re currently doing.
What it does: Works the quads in conjunction with the hamstrings and glutes.
Appears in: Body Beast – Beast Up Legs
- Stand with your feet shoulder-width apart holding a pair of medium-to-heavy dumbbells at your sides.
- Keeping your back flat, your chest up, and your core engaged, push your hips back, bend your knees, and lower your body until your thighs are parallel with the floor. The dumbbells should be several inches forward at the end of the movement.
- Reverse the move and repeat for reps.
What it does: Strengthens the quads in a lengthened position.
Appears in: PiYo – Buns
- Stand with your feet hip-width apart and your hands on your hips.
- Keeping your chest up and your core engaged, take a large step backward with your right foot, and lower your body until your left thigh is parallel to the floor. (Your right knee should be bent 90 degrees just above the floor.)
- Pushing downward through your right toes and left heel, raise your body several inches.
- Lower yourself again fully and “pulse” yourself upward a second time, repeating for a total of three pulses.
- Step your right foot forward to the starting position, and repeat the entire movement for reps.
- Switch sides and repeat, performing equal reps on each.
Front to back lunge
What it does: Builds unilateral strength and size in the quads, glutes, and hamstrings, while challenging full-body balance.
Appears in: Body Beast – Bulk Legs
- Stand with your feet hip-width apart holding a pair of medium-weight dumbbells at your sides.
- Keeping your chest up and your core engaged, take a large step forward with your right foot.
- Slowly lower your body until your right thigh is parallel with the floor and your left knee is bent 90 degrees, just above the floor.
- Pause and, pushing forcefully off your right foot, reverse the movement, taking a large step behind you without touching your foot to the floor in between.
- Again lower your body and repeat the entire sequence for reps, planting your foot only for each lunge. Then switch sides, performing equal reps on each.
Knee drop lunge
What it does: Strengthens and builds the quads, glutes, and hamstrings.
Appears in: 22 Minute Hard Corps – Cardio 3
• Assume a “prisoner squat” position: hands behind your head, elbows wide, knees and hips bent into a half squat. This is your starting position.
• Keeping your back flat and your core engaged, step backward with your right foot and place your right knee on the floor.
• Follow with your left knee and assume a kneeling position.
• Step forward with your right foot, then your left foot, and return to the starting position — that’s one rep.
• Repeat the entire sequence, starting this time with your left foot and continuing to alternate your lead leg on each rep.
What it does: Improves explosive power in the quads, glutes, and hamstrings; challenges coordination and athleticism.
Appears in: Shaun Week – Insane Weights
• Stand with your feet shoulder-width apart, and drop as low as you can into a squat position: legs bent, hips back, chest up, back flat, gaze forward.
• Explode upward, jumping off the floor and rotating 180 degrees in midair to your right.
• Land softly, immediately dropping again into a squat.
• Repeat the movement, this time rotating 180 degrees to your left.
• Continue jumping and squatting, alternating directions for 30 seconds.
Bear kicks (with hold)
What it does: Works the quads while activating and strengthening the glutes, building core stability.
Appears in: Shift Shop – Strength: 25
• Assume an all-fours position on your palms and the balls of your feet. Your back should be flat, your hands below your shoulders, and your knees bent 90 degrees below your hips a couple of inches above the floor.
• Keeping your toes pointed toward the floor, extend your right leg directly behind you until it’s straight and parallel with the floor.
• Return to the starting position and repeat with your left leg.
• Continue alternating sides for 1 minute, keeping your knees off the floor for the duration of the set.
What it does: Emphasizes the lowest, most challenging portion of the squat exercise, building strength and endurance in the quads, glutes, and hamstrings.
Appears in: FOCUS T25 – Lower Focus
• From a wide stance, drop into a deep squat position: knees bent, chest up, back flat, hips low, gaze forward. Press your palms against one another at your chest in prayer position.
• Keeping your back straight and your chest lifted, rise two inches from the squat position.
• Reverse the move and repeat, performing mini-pulses in and out of the deep squat position for 30 seconds.
Bulgarian split squat
What it does: Works the quads (along with the glutes and hamstrings) through a compete range of motion, while also providing a dynamic stretch in the hip flexors and quads of your back leg.
Appears in: Body Beast – Beast Up Legs
• Stand facing away from a box or bench holding a pair of light- to medium-weight dumbbells at your sides, and place the toes of your left foot on the bench behind you.
• Keeping your torso upright and your gaze forward, lower your body until your right thigh is parallel with the floor (your left knee should not touch it).
• Reverse the move, and repeat for reps, then switch sides. Perform an equal number of reps on each.
Lunge squat progression
What it does: Builds explosive power in the quads, glutes, hamstrings, and calves; improves full-body coordination and athleticism.
Appears in: FOCUS T25 – Lower Focus
• From a hip-width stance, jump and rotate 90 degrees in midair to your right, landing in a lunge: right foot in front of your left, right thigh parallel with the floor, both knees bent 90 degrees. Your left arm should swing in front of you, your right arm behind you.
• Explode out of the lunge position, jumping 90 degrees back to your left into a forward-facing shoulder-width stance.
• Immediately jump a few inches off the floor, landing in a wide stance, and drop into a squat with your hips back, chest up, back flat, and palms together at shoulder level.
• Explode out of the squat position, jumping back to a shoulder-width stance.
• Immediately, jump again, rotating 90 degrees in midair to your left, and landing in a lunge, this time with your left foot forward.
• Explode out of the lunge position 90 degrees back to your right into a forward-facing shoulder-width stance, then jump into a squat, and finally the shoulder-width stance.
• Continue cycling through the entire sequence for 30 seconds, performing an equal number of lunges on both sides.
The Muscles of the Quads
The quads are four distinct muscles on the front of your thighbone (femur): the rectus femoris, the vastus lateralis, the vastus medialis, and the vastus intermedius.
• The rectus femoris originates at two points on the pelvis, runs down the front of the femur, and attaches to the kneecap (patella). Unlike your other quad muscles, it crosses two joints — the hip and the knee — and you’ll feel it working (and possibly cramping) when you lift your leg straight up in front of you.
• The vastus lateralis is the meaty muscle on the outside of your thigh, the one that sweeps outward on a beefed-up bodybuilder’s upper leg. It originates at the top, outer portion of your thigh, and attaches to the kneecap and tibia.
• The vastus medialis is the teardrop-shaped muscle visible just above and to the inside of the knee. It runs along the inside of your femur, and is particularly active as your legs lock out.
• Finally, the vastus intermedius is the George Harrison of the group, quietly doing its job while obscured beneath and between bigger, flashier players. It runs along the center of your femur, underneath the rectus femoris.
While you’re hammering your way to becoming Quadzilla, however, remember that the best quad workout in the world is only as good as your ability to recover from it. So after you crush it in the gym with a serious quad workout, be sure to supply your body with the macro- and micro-nutrients it needs to rebuild and repair the muscle tissue you broke down during your uber-tough quad workout.
