If it was 48 hours after the workout I'd say that it was delayed onset muscle soreness which is totally normal when the muscles have been overloaded. However, I don't know of anything that would affect them up to 5 days later:confused: . I wouldn't go to the gym and work through the pain with weights but some gentle cardio and stretching will help with recovery as it increases bloodflow to the area. Maybe use the crosstrainer or rower very lightly and then stretch very well afterwards?
Hi I restarted body pump classes in January after about a 7 month break of doing no weights at all, just cardio (initially stopped due to injury, then just never got back into going to BP). Stupidly for my first class back I started off doing the squats at the same fairly heavy weight I'd been used to using all those months before. Went back to lighter weights than I'd been used to before for the rest of the class, but it was too late - my thighs were shaking so much after the class that I could hardly walk down the stairs! The muscle soreness in my thighs for the following days was horrendous, I was wincing every time I went to sit down (much to the amusement of my work colleagues!!), and the soreness didn't disappear fully until 6 whole days afterwards. I was fine after the class the follwing week however. I agree with blackjack's advice for gentle cardio and try to stretch as much as possible, and you'll be fine next week!
