Let me do the math. If you watch TV for.... maybe 30 minutes on Monday and in Tuesday maybe 25. Wednesday another 30 and Tuesday 15. So add it all up and you get 1 hour and 35 minutes how many seconds are in 1 hour and 35 minutes? Well with some quick and easy multiplication ( 30 x 60 = 1,800 + 60 x 60 = 3,6000. Add it all up and you get 5,700 seconds. Meaning 5,700 push-ups . And they many push-ups would build about 1.15LB of muscle, and about 3,020 calories burned.
