I'm 6' with trex arms and not particularly athletic, but I made it my mission in my early-mid twenties after experiencing the exhilaration of a late bloomer who could finally get results in the gym. When I was 25 I could cheat where I grabbed the rim with my off hand and slammed it with the other, which is stupid but goddddddd I was so proud. I'd love to feel that spry again. Treasure your twenties, guys.
