I'm 40. Does anyone else do any weightlifting or even cross training? I was weightlifting for a couple of years and it helped my skating a lot. I haven't been able to lift for the past few months due to Covid lockdowns (no dine-in, no theaters, no gyms, no playgrounds, no skateparks, etc.). As a result, I lost a lot of size, weight, and most importantly strength, which sucks. Skating definitely got harder. I feel heavier and get tired faster, and I never had a jumpers knee problem but I do now, so I started stretching and doing some body squats and this yoga pose that's supposed to help with knee strength that I saw in a YouTube video.
Weight training and stretching are the secret ingredients for sure.
