I'm in my mid 30's and I just started practicing handstands a few months ago. Before that I had to get my weight under control first.
Just a comment about this from a 90% self taught gymnast whose weight is what it is at any point in time ... the last time I did a beautiful, straight leg cartwheel (on land), I was 5'3" and about 450 lbs.
I learned a one-handed cartwheel at 4'9" and 180 lbs. I also learned a handstand into a bridge on a low balance beam that same year.
I am in my late 40s now and I weigh less than I did in January of 9th grade. I can still do the splits (right leg forward) with only minimal warm up / stretching.
I am not allowed to do any of the "fun stuff" unless I am in water, so I practice roundoffs and back handsprings whenever I go swimming.
Water is great for practicing handstands.
