Handstands OK on rest days?

Or will this over-fatigue my shoulders from my workout days (in which i do HSPU)

Test it out and see. I've been doing it and I haven't felt overtrained at all.

Have you tried it? You will learn a lot by doing a little experimenting....

 

Once you are strong enough HS is a skill and can be worked way more frequently than strength. Some days may be heavier than others, but if handstands are significant work for you then you need to have rest days and slowly add it in. Try doing HS training on your rest day this week and see how it effects your HSPU training. Then try resting on your rest day next week and see how that effects it.

 

If you do a little trial and error before posting a very open ended question (especially when it comes to programming), you will have much better feedback from moderators and forum members because your questions will be more direct. And 9 times out of 10 you will answer your own question . Because right now a moderator would have to ask lots of questions about your training background and current level of strength and spend a lot of their time prying information out of you to actually help you. Just a little heads up.
