Does anyone see any need for shoulder weight training if you do handstand pushups? If your goal is generally strength, stability and athleticism (so not bodybuilding/figure etc).
There are lots of different ways to work your shoulders with weights. Are there any that you consider important - over and above doing HSPU's?
Or perhaps looking at it another way, what HSPU variations (or other bodyweight exercises) would you use to ensure no weaknesses/imbalances develop?
Even answers from a bodybuilding perspective will be very helpful as bodybuilders are probably best versed about what movements/exercises work which muscles.
