If the only exercise you did in a day was pushups, a decent target for general health would be roughly 50 to 150 pushups across the day, done in multiple sets that are challenging but still controlled. That is not because pushups are a complete exercise program. They are not. It is because pushups can at least provide your body with some meaningful muscular work for the chest, shoulders, triceps, core, and upper-body stability, which is far better than doing absolutely nothing. Public health guidance still recommends a mix of aerobic activity plus muscle-strengthening work involving all major muscle groups on at least 2 days per week, so pushups alone do not fully cover what the body needs for health.
A good way to think about it is this: if a person did very few pushups, such as 5 to 20 total in a day, that would be better than none but probably too little to create much whole-body benefit unless that amount was already very hard for them. On the other hand, if someone managed 50 to 150 total pushups per day, spread over several rounds, that would at least give them a modest daily dose of resistance exercise. For a beginner, that might mean 10 sets of 5. For someone more trained, it might mean 5 sets of 20, or several mini-sessions throughout the day. The exact number matters less than whether the sets are difficult enough to feel like real muscular work. Current guidance emphasizes that any resistance training is better than none, and that the biggest gains come from going from inactive to consistent, simple training.
Still, if pushups were literally your only movement, there would be major gaps. Pushups do almost nothing for your cardiovascular system compared with sustained walking, cycling, or other aerobic activity. They also do not adequately train the legs, hips, glutes, lower back, or many of the pulling muscles of the upper body. Health guidelines specifically call for activity that covers more than one physical quality because the body benefits from endurance work, muscle work, movement variety, and reduced sedentary time. So even a very impressive pushup total would not fully replace normal movement.
If the question is not “What is ideal?” but rather “What is the minimum number that would still give a decent level of health if pushups were all I did?”, then the most honest answer is this: around 75 pushups per day is a reasonable middle target for many healthy adults, assuming they are broken into clean sets and done consistently. That amount is high enough to be real work, low enough to be realistic, and enough to maintain at least some upper-body strength and muscular endurance. For stronger people, 100 to 150 per day would be a more solid benchmark. For beginners, 30 to 50 per day may already be enough to count as a decent starting dose, especially if full pushups are hard and the sets are near fatigue.
The smartest way to do this would be to avoid chasing one giant set and instead spread the work across the day. For example, 10 pushups every hour for 8 to 10 hours gives you 80 to 100 total without crushing your joints or technique. Another option is 5 to 8 hard sets, stopping when form starts to break down. That approach is more likely to give you useful muscular stimulus than doing a random number with poor form. Since guidance for muscle-strengthening emphasizes working hard enough that another repetition becomes difficult, effort and quality matter more than just collecting repetitions.
So, in plain language, here is the answer. If pushups were truly the only exercise you did, 50 pushups per day is a decent bare-minimum floor, 75 to 100 per day is a more respectable health-oriented target, and 100 to 150 per day is a stronger target for people who already have the capacity for it. But even then, that would still be a narrow form of fitness, not a well-rounded healthy routine. It would give you some benefit, and some benefit is absolutely better than none, but it would still leave large parts of your health undertrained.
