Push-ups was one area of excercise in which I would always struggle - even at a time when I was a top competitive swimmer and also area Kendo, lots of cicling, running. I was fit. But pushups always a struggle. Solution - do pushups at an angle, so use a chair pushup from that (a comfy sofar arm rests even better and perhaps safer as well). This does mean you are using less effort, but you are still working those muscles and will be able to gradually lower the angle. Bigger the angle, less effort (yay science). So even those with extremely weak muscles involved in a pushup, can do them without struggling and exerting themselves as well as possible injury trying the usual style push ups. TL;DR Push Ups involve muscles that you may not use in other sports and activities. Push Ups at an angle can aid those with weak muscles who struggle to do a normal pushup and aid them in building the muscles up to the level that will enable them to do a normal pushup.
