So I got a bike trainer for Christmas!

It’s a Giant Mag 2 trainer. It’s a weird experience. The resistance is adjustable but it doesn’t seem to go high enough for my liking. I do sweat after awhile but it doesn’t seem very hard. I guess the point is simply to spin with minimal resistance. This isn’t, as I had thought, a replacement for a spin class. The level of resistance is completely different. It also seems like I have to use a pretty high gear because the resistance at lower gears isn’t enough to keep the spin steady.
Overall, it’s better than riding in the rain but not as satisfying as a real ride or spin class. These contraptions are also expensive.
