intervals...do they have to be done on the bike
Second year rider here with modest goals. Lose weight (currently 245) and increase speed (currently 13-14 on relatively flat rolling terrain).
I have been building base for 2 months now, riding when I can and in a gym when too cold. Keeping hr between 130-150 for 60-90 mins, 4 times per week. Riding between 75 mins and 3 hours now that it is warmer (in NC).
Question is, I have been told that when I switch from base to intervals (very soon), I MUST do the intervals on the bike.
Why? For that kind of measurable effort, I prefer the controlled environment of the gym. (Elliptical, stationary bike or stair stepper)
Any suggestions on how to succeed at intervals on the bike would be greatly appreciated. I have tried it once or twice and really did not enjoy it. I love riding, but structured training seems like no fun at all on a bike.
