idk what it is, maybe my diet idk but heres my situation
i'm a league bowler
lately, i've been getting really sore after bowling, especially high up in my inner thigh. i've been bowling forever, and this never used to happen to me. the only things i can think that have changed are that i've been going a couple more times per week, and i haven't been eating very many vegetables, but idk if either of these should cause this lasting problem. i usually try to stretch out, but i'm still getting these sharp pains, maybe i'm not stretching out the right muscles, idk.

anyway my average is suffering in game 2 and 3 lmk if u got any advice

What lifts at the gym are you doing?

Do you warm up?
Do you stretch?
Do you do any strengthening exercises?
Proper diet will help slightly.
Do you use a different technique that is abnormal to your usual?

no i don't really lift, i jog but that's it

i dont warm up either, i do stretch though before bowling, last time i did that butterfly thing and that helped

i used to bowl alot, streching helped me out back then.

doing more strenuous activity than you're used to will usually make you sore but you'll stop getting sore as time goes on
that being said if you're getting sharp pains it could be a tweak or perhaps a muscular imbalance developed from bowling, doing the same movement unevenly over and over will eventually lead to imbalances (using the same hand every single time you bowl etc)
