Just as the title says. I'm good for about 15 minutes at 3.2mph. Around that time the muscles on the left side of my shin on my left leg start to burn and hurt to the point that I have to step off the treadmill or I just about fall down.
Is this caused by a lack of potassium or does it seem like I may have muscle damage?
Any insight will be appreciated.
Thank you in advance for your replies.
