Title says it all.
Considerations:
I used to do cardio, burning between 1000 to 1500 kilocalories in one session 1 hour to 1.5 hours, which is deemed beginner to intermediate for endurance training with running.
Short and kind of bulky at 67kg for 1.65m, or 147 lb and 5'5".
Running is not the best option and won't be the best option for the next 2 or 3 years for obvious reasons.
So I'd rather do something new, like push-ups.
Any plan on how to burn the same amount of calories with push-ups in a similar timespan?
