i have a cyclops mag trainer, i am using dvd's also. what i have been doing is just cranking the resistance all the way up elevating the wheel on front and spending 2hrs on it 3 -4 days a week . by the way my legs feel when i am done after 30 miles and doing intervals with the dvd's i feel like i did a good ride. i have noticed when i get out on the road things feel really good. anyone else take this approach? i have just been concerned with going to light on the trainer , and when weather permits riding that i will end up getting dropped. i alos dont want to overtrain. any thoughts?
