I don't do the gym scene (can't afford it due to other financial obligations). I have an old Turbo Trainer wind trainer that I ride after work three to four times a week (I don't like riding on the road after dark on south Louisiana's narrow roads). I use a Cateye Astrale 8 computer with a rear wheel-sensor and a Sigma PC14 heart monitor to track my performance. I listen to music while training and alternate interval workouts with tempo/recovery rides. Sometimes I'll ride my rollers for a change of pace or do upper-body workouts on my wife's Schwinn Aerodyne. I also do "vee-sits" to tone my core. Lucky for me it stays warm enough down here that I can get in some road work on the weekends (schedule permitting).
