Nope. 6 months ago I struggled to do one push up, which is kinda crazy. Also slightly worrying.....i think everyone should probably be able to manage one push up
The particularly impressive thing to me is that it's taken less than 5 mins of my day, just consistency.
Also, up until now it's just been straight unweighted push ups but it's clearly increased my strength beyond that load
It's extrapolating a lot, and presuming that my son was placed on my back so I was lifting his entire weight, but if you put 8x66kg into a 1 rep max calculator that works out as 83kg, or 1.27x my bodyweight which is apparently a half decent bench press (I admittedly don't know whether a push up translates as an upside down bench press )
