Knee issues are very common with skaters, especially those who begin to skate a lot or start doing longer distances before their leg muscles are strong enough to support the joints properly.
Skating correctly demands that the leg muscles do a huge amount of work compared to being sedentary, so it’s very common for new skaters to complain of knee and leg pains when they suddenly begin to skate and increase their skating intensity or frequency.
Let me know via social media how these exercises felt to you.
I’m hoping to motivate you to supplement your skating with other strength building movements so you gain the benefits of cross training and avoid repetitive strain (slow-onset) injuries from your skating.
