I am down the Gym quite often , and they have a spinning class there. I could not see the sense of just spinning at fast speeds, when I can do that on my mountain bike on rides. Last Night I tried a class, and joined in. No pressure, do what you want to at the level you want to, and slow down if necessary. I thought I was fit, but this was the hardest workout I have had all winter. 1 hour with the heart rate running at 90% for the whole time. I know that is how I normally ride to enable me to stay with the youngsters, but I do have a few rests at the top of hills waiting for the rest. Not on that spinning class though. No rest, slacken off for a bit occasionally, but work- work -work was the by word of the night. It may have been because I am a cyclist so I did not want to be shown up, but as I say, it was the best workout of the winter. I have booked in for the next 6 weeks classes now, but I won't be doing the 2 hours gym and weights work beforehand.
If any of you have the chance to join in on this type of class, Do it
By the way, My legs were killing me this morning.
