Bike trainers are nice, I have one and use it from time to time. They are great for HIT type workouts!
And remember, consistency is the magic pill!
I get the consistency, fell like with exception of last week I have been.
the trainer is love hate for me. I love the fact that I am not outside on the bike in 18 degree temps. But HATE not actually moving, I'd try rollers but I don't wanna die in my living room
