Standard push ups are boring. There, I said it. If you have spent any significant time in a gym or grinding through bodyweight circuits in your living room, you know the feeling of hitting a plateau where the basic movement just doesn't bite anymore. That is exactly where the Spider-man push ups come into play. It is a deceptively simple tweak to a classic exercise that turns a chest workout into a full-blown metabolic nightmare—in a good way.
Most people see the "Spider-man" name and think it’s just a gimmick for Marvel fans. It isn't. When you bring your knee toward your elbow during the descent, you are shifting your center of gravity and forcing your obliques to scream for mercy. It’s hard. It’s awkward at first. You will probably wobble. But that instability is exactly why it works.
The anatomy of the move
Let's break down what is actually happening in your body. When you perform a regular push up, your core acts as a bridge. It’s a static hold. But with the Spider-man push ups, you turn that bridge into a moving suspension system.
As you lower your chest toward the floor, you are simultaneously drawing one knee out to the side and up toward the ipsilateral elbow. This creates a massive amount of lateral tension. Your serratus anterior, those "finger-like" muscles on your ribs, have to work overtime to keep your scapula from winging out.
Honestly, the biggest mistake people make is rushing. Speed is the enemy of the Spider-man variation. If you're just flailing your legs around, you’re missing the point. The goal is to synchronize the knee drive with the eccentric phase of the push up. You should hit the bottom of the rep at the exact moment your knee is closest to your arm.
Why your obliques are the secret sauce
In a standard plank or push up, you’re mostly fighting extension. You don't want your hips to sag. However, the Spider-man push ups introduce a rotational and lateral challenge. This engages the internal and external obliques in a way that traditional floor presses or even standard diamond push ups simply cannot touch.
Think about it this way. You’re essentially performing a mountain climber and a deep chest press at the same time, but without the momentum. Dr. Stuart McGill, a world-renowned expert in spinal biomechanics, often talks about "core stiffness." This move builds exactly that. It teaches your trunk to stay rigid while your limbs are moving through different planes of motion. It’s functional as hell.
Avoiding the common "ego" mistakes
I see it every day. Someone tries to look cool in the gym, they start cranking out reps, and suddenly their form looks like a wet noodle.
- The "Butt in the Air" Syndrome: Because this move requires extra hip mobility, people often hike their hips up to make room for the knee. Stop doing that. Keep your back flat. If you can't get your knee to your elbow without sticking your butt up, just bring the knee halfway.
- The Sagging Hip: On the flip side, as you get tired, your pelvis will want to dip toward the floor on the side of the moving leg. This puts a lot of shear force on the lumbar spine. If you feel a pinch in your lower back, you've gone too far.
- The Short Rep: People get so focused on the leg movement that they only go down two inches. A Spider-man push up is still a push up. Your chest needs to get close to the floor.
It is also worth noting that your wrist health matters here. Because you’re shifting weight side-to-side, there is more pressure on the carpal bones. If you have "crunchy" wrists, try using hex dumbbells as handles to keep your wrists in a neutral position.
Does it actually build more muscle?
Yes and no. If your only goal is massive pec hypertrophy, a bench press or a weighted dip is probably more efficient because you can load more weight. But if you want "useful" strength—the kind that translates to wrestling, climbing, or just being a more capable human—this is superior.
The Spider-man push ups increase the time under tension for each rep. Because of the coordination required, you naturally move slower. Slower reps mean more muscle fiber recruitment, especially in the stabilizing muscles of the shoulder girdle.

Variations for the brave (and the struggling)
Not everyone can jump straight into the full version. That’s fine.
If you're struggling, try the "Staggered Spider." Instead of moving your leg while you push, move the leg first, hold it, and then do the push up. It’s like training wheels for the coordination part.
For the high-level athletes, try the Spider-man push ups on a medicine ball. Putting both hands on a single ball or one hand on a ball while the other is on the floor adds a level of proprioceptive demand that will make your triceps shake like a leaf.
Another killer variation is the "Slow-Mo Spider." Take a full three seconds to descend, hold the knee-to-elbow position for a second at the bottom, and then explode up. You’ll find that five reps of this feel harder than fifty regular push ups.
The metabolic "Afterburn"
Let’s talk about fat loss for a second. We know that "spot reduction" is a myth. You can't do a thousand push ups to lose chest fat. But, compound movements that recruit multiple large muscle groups simultaneously create a higher metabolic demand.

The Spider-man push ups are a "big" move. They require the heart to pump blood to the chest, triceps, shoulders, and the entire hip complex all at once. This increases the oxygen debt you incur during the workout. This is often referred to as EPOC (Excess Post-exercise Oxygen Consumption). Basically, you're burning more calories while sitting on your couch later because you did the hard work earlier.
Integrating this into your routine
Don't just swap out all your chest work for this. It’s a tool.
I usually recommend placing Spider-man push ups toward the middle of a workout. You want to be warmed up—your hips need to be "greased"—but you don't want to be so exhausted that your form breaks down immediately.
- As a finisher: 3 sets to failure at the end of a chest day.
- In a circuit: Mix 10 reps with kettlebell swings and pull ups for a full-body blast.
- As a mobility-strength hybrid: Use them during your warm-up (low intensity) to wake up the core and hips.
Reality check: It’s not for everyone
If you have a history of labral tears in the hip or significant impingement in the shoulder, be careful. The "out and up" motion of the leg requires significant external rotation in the hip. If your hips are tight from sitting at a desk all day, you might find this move actually irritates your hip flexors before it helps your chest.
Always listen to your body. There is a difference between the "burn" of a muscle working and the "sharpness" of a joint failing. Learn to tell the difference.

Actionable Next Steps
To actually master the Spider-man push ups, you need a plan that doesn't involve just "trying it once" and giving up when it feels weird.
- Week 1: The Hip Opener. Before you even try the push up, get into a plank and just do the leg movement. Focus on keeping your back flat. Do this for 3 sets of 10 reps daily to build the hip mobility and oblique activation.
- Week 2: The Eccentric Focus. Start from the top of a push up. Lower yourself slowly while bringing the knee up. Once you hit the bottom, drop your knees to the floor to push back up. This builds the strength for the "down" part without the struggle of the "up" part.
- Week 3: The Full Rep. Aim for 3 sets of 5 reps per side. Quality over quantity. If your hips sag on rep 4, stop the set.
- Check Your Hands: Ensure your hands are slightly wider than shoulder-width and rotated slightly outward. This creates a more stable "tripod" for your shoulders to rotate within.
- Film Yourself: This is the most important part. What feels like a straight back usually isn't. Use your phone to record a side profile and check if your hips are hiking or sagging during the transition.
