Do 100 push-ups daily for 100 consecutive days

got threw day 5 and it keeps getting harder. i have even tried to start pacing myself better, won’t let myself do more than one set of 10. still around 70-80, it just gets ugly. tried to do some basic lifting afterwards and i could dumbbell press 25 pounds twice after.

also doing 100 situps a day too. 2nd day was harder than the first but easier than situps. Maybe because i have better upper body strength. (and i did the situps first).

Also bought a bench for my home gym today. so i will be lifting after situps some days.
