Which push-up angle works which muscles best?
Angle-specific upper body muscle activation in suspension push-ups: an electromyographic analysis across different body angles

Surprising Findings
TRX doesn’t boost triceps in decline push-ups — floor versions work them harder.
Most assume instability always increases muscle demand, but here, stable decline push-ups produced the highest triceps activation (41% MVIC), and TRX added no further benefit.
Practical Takeaways
Do incline TRX push-ups (+30°) to maximize chest activation.

If you're doing push-ups and your feet are elevated (making it harder), your chest muscles don't work as hard. But if your hands are higher than your feet (like on a bench), your chest has to do more of the work—especially when your body is flat.
If you're a guy who works out, doing push-ups with your feet elevated (like on a bench) makes your shoulders, arms, and upper back work way harder than regular or uphill push-ups — the steeper the angle, the harder those muscles have to work.
If you're a guy who works out, doing push-ups with TRX straps might make your chest muscles work harder than regular push-ups—especially when you're more upright, like on a slight incline.
If you're a guy who works out, doing push-ups at a 30-degree downward angle makes your shoulder-stabilizing muscles work way harder—up to 2.5 times more—than flat push-ups, no matter if you're on solid ground or using suspension straps.
If you're a guy who works out, doing push-ups on a decline with a stable surface fires up your triceps the most — more than using shaky suspension straps like TRX when your body is already at a steep angle.
