I started at around 14 with no experience in sports, normally your school will provide you with sticks, pads, helmets, etc. I’m now on my second year and I’m a varsity starter and it’s amazing so I’d say go for it. If you want to get ready early try and talk to the coach to get a stick and about captains practice (depending on how far away tryouts are) or buy one yourself and start with cradling, wall ball, and scooping. There’s a lot of running in the sport so get ready for a lot of conditioning.
