Funny I was just going to post about Spinervals and the value of a cadence sensor.

We have from the competition series: No Slackers Allowed, The Uphill Grind, Aerobic Base #1, Sufferarama, Muscle Breakdown, Recovery & Technique and Mental Toughness.

I do stand on the bike while it's in the trainer.

Personally I think the hardest ones are Sufferarama, Muscle Breakdown and No Slackers in that order.

We've just put the cadence sensor back on the bike in the trainer and that makes the workout MUCH harder. When he tells you to spin at 120 RPMs you know whether you're doing it or not. No guess work and it is HARD.
