As you lower your chest toward the floor, one knee travels out to the side and toward the elbow on the same hand, similar to the climbing crawl of the character the exercise is named after. The fist position keeps your wrists stacked and straight, which many lifters find friendlier than a flat palm on a hard floor, and it also strengthens the forearm and wrist stabilizers along the way. This movement trains three things at once: pressing strength through the chest, triceps, and front shoulders; hip mobility and oblique control as the knee drives toward the elbow; and anti-rotation core strength, because lifting one knee off the floor tries to twist your hips every rep. The core demand is noticeably higher than a standard push-up, since you are essentially holding a plank on three limbs while moving the fourth. The setup matters more than in a regular push-up. Because you are balancing on fists, your hands need to sit directly under your shoulders with the knuckles flat against the floor, and your body needs to stay rigid from head to heel. If your hips sag or rotate when the knee comes up, the press turns sloppy and your lower back takes the load. A straight, braced torso is what makes the knee drive hit the obliques and hips instead of stressing the spine. To perform it well, think of the press and the knee drive as one coordinated action: lower until your chest is near fist level while the knee slides toward the elbow, then push the floor away and return the foot to the starting position together. Alternate sides each rep or complete all reps on one side before switching, depending on your goal. Controlled tempo beats speed here, because the knee drive is where the form usually breaks down. This variation suits lifters who already own solid push-ups and want more core and hip involvement without extra equipment, as well as martial artists and grapplers who benefit from knuckle conditioning, hip mobility, and pressing from an unstable base. Common use cases include body weight strength circuits, warm-up progressions for harder push-up variations, and conditioning work where floor space is the only requirement. If full push-ups are still a struggle, build the base version first before adding the fist and knee drive. ## Instructions 1. Kneel on the floor and place your fists shoulder-width apart, knuckles down, wrists stacked directly under your shoulders. 2. Step your feet back into a high plank with your legs straight and roughly hip-width apart, forming one straight line from head to heel. 3. Squeeze your glutes, brace your abs, and press your knuckles firmly into the floor so your fists stay flat and your wrists do not bend. 4. Inhale and begin lowering your chest toward the floor by bending your elbows at about 45 degrees from your torso. 5. As you descend, draw one knee out to the side and toward the elbow on the same side, keeping the foot off the floor and your hips level. 6. Pause briefly when your chest is a few inches from the floor and your knee is close to its elbow. 7. Exhale and press the floor away, straightening your arms while you return the foot to the starting plank position. 8. Repeat with the opposite knee, alternating sides rep by rep, or finish all reps on one side before switching. 9. Keep the tempo slow on the way down, roughly two seconds, and reset your brace and plank position between reps if your hips start to sag. ## Tips & Tricks - If your knuckles hurt on a hard surface, use an exercise mat or do the movement on a rubber gym floor; a folded towel under the fists also works. - The most common mistake is the hips twisting toward the moving knee. Point the knee slightly outward and think of pushing the opposite hip down to keep your pelvis square. - Keep the knee drive below the elbow rather than past it; chasing the knee to the elbow too early usually collapses the shoulder and rounds the lower back. - If your wrists collapse inward, widen your hands slightly and focus on gripping the floor with your fingers so the forearm stays vertical. - Shorten the range by doing the knee drive from a lower-stress position first if your press fails before your core does; the limiting factor tells you which part needs work. - Do not let the head drop or poke forward as the knee comes up; keep your neck neutral by looking at a spot on the floor about a foot in front of your fists. - Slowing the descent fixes most reps. Rushing this exercise turns the knee drive into a jerk that robs the obliques of the work. - Spread the load across the first two knuckles, index and middle, rather than rolling onto the outer edge of the hand. ## Frequently Asked Questions ### What muscles does the Fist Spiderman Push Up work? The primary work comes from the chest, triceps, and front shoulders during the press. The knee drive adds the obliques, hip flexors, and deep core, while the forearm and wrist stabilizers work hard because you are balanced on your fists. ### Why do the push-ups on fists instead of open palms? The fist keeps your wrist perfectly straight, which removes the backward wrist bend of a flat-hand push-up and loads the forearm muscles instead. It also builds knuckle conditioning, which is useful for combat sports. ### Is the Fist Spiderman Push Up suitable for beginners? Not as a starting point. You should be comfortable with at least 15 to 20 clean standard push-ups before adding the fist grip and knee drive. Beginners can practice the knee drive from a plank first, then progress to pressing on fists. ### Should I alternate knees every rep or do one side at a time? Alternating sides each rep keeps the workload even and is easier to count. Doing all reps on one side first makes each set feel harder on the obliques, so choose based on whether you want balance or intensity. ### My hips rotate every time I bring the knee up. How do I fix that? Slow the knee drive down and reduce how far the knee travels before it pulls your pelvis. Brace your abs hard before descending and keep the opposite foot pressed into the floor as an anchor. ### Can I substitute the Fist Spiderman Push Up if it is too hard? Yes. Do a regular Spiderman Push Up on open palms, or perform the fist version with your knees on the floor to reduce the press load while keeping the knee drive. Both keep the same movement pattern with less demand. ### How close should the knee get to the elbow? Aim for the knee to reach the outside of the elbow at the bottom of the rep, but only as far as you can go without your hips rotating or your chest stopping short of depth. Depth of the press takes priority over the knee travel. ### Are knuckle push-ups safe for the hands? For most people they are fine when the fists are flat, the first two knuckles carry the load, and the surface is not sharp or uneven. If you have a wrist or hand injury, stick to open palms or use push-up handles instead. ### How many reps should I do of the Fist Spiderman Push Up? Because the core demand is high, most people get quality work in sets of 6 to 12 total reps. Stop the set when your hips start to sag or the knee drive becomes uneven from side to side.
