Re: Has anyone drastically improved their vert in their 20s?
You can definitely still improve your vertical. I started using a jump manual for the first time when I was about 25 and within 5-6 weeks I was able to jump 4 inches higher. My brother even hit his vertical jump peak in his 30s. But obviously it depens on whether you've done vertical jump training before, because at some point it gets harder to improve (regardless how old you are). Once you get older you obviously loose a step or two but the biggest difference imo is that your body can't take the same amount of hard vertical jump training anymore. You will experinece little injuries every once in a while and you will have to listen to your body more carefully.
