Good job! Keep at it a it you'll get it back and more! When I got back on the bike I read "Ride Your Way Lean" by Selene Yeager. I think she also writes for Bicycling magazine...
I really got inspired and pumped by reading just a little over half way. It talks about all the great things you're doing when you get back in the saddle. I can't speak with experience for her actual workout because I made my own up that works for me.
