Re: Recommend Supplement for pre/post cycling? [newbie]
The best thing to help your legs (especially knees) is to ensure your bike is set up correctly. Most cycling related injuries are due to poor bike fit and upping the mileage too soon. To be honest for an hour on the bike all you require is water. You're only looking at replenishing electrolytes on long rides around 3 hours or so unless you're cycling in a very hot or humid environment. You would have been better posting this on a cycling forum such as BikeRadar.
Well done on the weight loss.
