The Claim
Push-up intensity can be reliably adjusted to match 40% of one-repetition maximum (1RM) bench press through bodyweight modifications such as knee flexion or hand elevation, thereby enabling effective low-load resistance training without equipment.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
You can make push-ups easier or harder by changing how you do them—like bending your knees or putting your hands on a raised surface—to match the same effort as lifting 40% of your max bench press weight, so you can still build strength without any gym equipment.

What the research says
1 studyStudy: Low-load bench press and push-up induce similar muscle hypertrophy and strength gain
The study showed that doing push-ups with knees on the ground (or hands elevated) to make them easier — just enough to feel like lifting 40% of your max bench press — worked just as well as actually doing light bench presses to build muscle and strength.
