I'm gettin' older, no doubt. Running hurts my knees. I'm thinking of an exercise bike to keep my legs in shape, which should benefit my diving. Problem is, there's a shitload of them online. Anyone have any good or bad experiences or recommendations for a good one? I figure 15-20 minutes 3 or 4 days per week. I can put on the headphones, listen to about 5 Skynyrd or Blues songs and I'm done. Easy. And by Christmas I'll be able to dive as good as Jake. That prick....:D
