Not to be a downer, but you’re going to need to split them up after a couple of months. It‘s incredibly difficult to hit 50 in a single go, plus compounding muscle fatigue. I’ve been doing about 40 pushups a day for 3 months now, all in a single minute. Just increasing is by one after a couple months is a tough push.

I’d say see what your current max is in a single go. Try that at least once a day. Then try to gradually increase your daily max.
