I was thinking along these lines this morning in particular adaptation.acoggan said:"The more you train the more you can train." - A. Coggan
While I was on the spin bike the spin teacher was training on her off day for a 1/2 marathon coming up in two weeks. Here we are talking about physical limitations and yet I see many examples of these aerobic teachers in the gym that teach classes through out the day for a living and like this teacher also train for events.
I believe she does 3 or more spin classes every other day during the week and also runs everyday because that is her competitive event. She has a very energetic look and a positive attitude.
How does she and these other teachers endure such a load?
It really seems to say a lot for gradual adaptation through progressive training.
This has been true for me in weight training and over many years I can train with more than 20 sets per bodypart without over reaching. I just need to gradually build up in endurance events.
