Hi RWTD,
I understood that it is better to do the leg extensions at only 3/4 so as to avoid full lockout.
The day off idea is good. I have a tendency to push myself at times and think that I am whimping out if I stop whenever I feel pain but have since been learning that you should stop when you feel pain, especially when it is in a knee that has previously been injured.
I like the elliptical trainer as it give me a break from the cycling and muscles are being used in a different way.
I always wondered if cycling everyday could strain the muscles over time or could lead to them becoming so used to a particular motion that your are no longer benefitting in the same way from that particular exercise. Not sure if I am explaining this properly though.
