I'm a lazy bum in the winter, and I've put on all the weight I lost over the summer. Additionally, I miss being on a bike and the feeling in my legs after a good ride. So, since my brother had a spare he left at my parents place, when he offered to let me grab it a couple weeks ago when we were catching up, I jumped at the chance.
It took me a week or two to get around to flipping the tires on my bike (I'd replaced the rear tire with something a bit nicer after I flatted out and punctured the tire itself, and I wanted to get rid of the bright red tires it came with anyway for cosmetic reasons), since trainers are evidently hell on tires. I finally did that last weekend though, figured out how to set the thing up, and started riding.
On one hand, holy shit does it suck to ride inside in an enclosed area, with no headwind to keep you cool. Since there's not a constant wash of air over you from moving, sweat just beads up all over you, huge globulets of the stuff. The first time I rode it, there was a pool of sweat on the floor under me when I was done. The second time, I put down a towel, lol. Jon had warned me, but he really wasn't kidding.
On the other... Man, did it feel good to be spinning again, and the "I worked out yesterday" feeling in my legs as I walked up the stairs in my building today was something I'd really missed.
My buddy has a spinner he bought from Powerhouse in his living room he hits for 30 minutes every morning. I can't get used to riding stationary, especially at home. The gym is one thing, but in the living room just feels very odd.
