Anybody got a good cycling workout that takes about 20 minutes? I might have to buy an indoor trainer.
20 minutes is just warm up to get the legs loose and blood circulating. I'd say at minimum an hour for short intervals if you want a focused cardio workout. 4x10 min aerobic threshold with 5 mins rest (endurance level) between sets. Or the standard 2x20 with 10 minutes rest between sets. 20 minute warm up, 50 minutes workout and 20 minute easy spin = 1.5 hours. That's about as short as I can make a workout and get anything useful out of it.
