Bodyweight quad exercises

Why is this list so long?

Because almost every movement done on your feet bends and straightens the knee. Walking, running, jumping jacks and jumps load the quads with every step, so the catalog tags them with this muscle and the list swells. That is not a mistake, but as you read it, it helps to separate three kinds of entry.

The first group is strength work: squats, forward and reverse lunges, the Bulgarian split squat, step-ups, the kneeling sissy squat. The second is conditioning that tires the quads on the way past: burpees, high knees, jumps, walking and running. The third is stretching and mobility - the quad stretch, the butterfly, adductor openers. The first group builds legs, the second builds work capacity, the third does not load the muscle at all.

If you came here for quad exercises and not for a circuit, start with that first group and treat the rest as a warm-up or as a separate goal.

How do you load legs with no weight?

By taking legs away. A two-legged squat splits your body weight roughly in half, forward and reverse lunges move most of it onto the front leg, the Bulgarian split squat leaves the back leg nothing but a balancing job, and the skater squat and the pistol put practically all of you on one leg. That is the cleanest difficulty scale that exists without equipment, and it needs nothing but a chair.

The second direction is time under tension. A pause at the bottom, pulses in a lunge and an isometric hold against the wall turn a light movement into a hard set without changing the geometry at all. A wall sit does not look difficult until the first minute is up.

The third is range. The kneeling sissy squat and the Cossack squat put you in positions where the quad works deep in a stretch, which is why they can be demanding with zero external load. Learn both carefully, because they take the knee through a range not everybody is used to.
