For years i have done pressups/situps and chinups as part of my general fitness to go along with the running i do but recently after seeing some squaddies doing pressups im wondering if ive been doing it wrong 
When im doing pressups i have my hands roughly in line with my chest and shoulder width apart, when lowering down my elbows go outwards.
However squaddies seem to do them with the elbows at the side
See pic
Am i doing them wrong
Or is it just different ways of doing them?
Ive tried doing them keeping arms at the side and struggle to bang out 4 or 5
