@snacks@netzsphaere.xyz Could defo be, if you are not used to freeweight/bodyweight training your hitting muscles you usually dont hit with isolation exercises and machines.
I had this times 10 when i switched from calisthenics to ring calisthenics because those rely alot on those muscles.
Its a good sign(If you have proper nutrition/rest and warmup/cooldown) because it means your muscles are "growing"(muscle micro tears, which will be repaired in rest making the muscle stronger)
