Thanks all for the tips so I guess I'll just continue the home workouts that include weighted lunges, squats, and leg lifts for now and put a little more focus on the left leg. Just wasn't sure if there was anything I could do ON the bike.
As far as a pinched nerve what level of weakness would I have to see before I would consider that? This is the first leg workout I've done in a long time and outside of this workout I really haven't noticed my left leg being weak. When I ride, walk, hike, climb stairs etc. I just found it odd that the leg is a lot more sore than the right which would lead me to believe it's a lot weaker. I'll do some research on the topic for sure. I have my annual coming up and I think they do an EKG so I'll ask the doc about it to see if that would show any signs.
