just like riding a bike

I decided that since Monday is my pseudo off day (Sunday is the only day I am always off) that I would try something semi challenging, but go easy with it, so I went back to the stationary bike. I did 4 reps of bike sprints. I bike 1:30 at 85-92rpm, the I pedal as fast as I can for 30 seconds (125-133rpm). I did it four times. This workout is like the team sprints we do at Mark's driveway, or the hill sprints, or the route running I did at Vollrath Park last week, as well as the cross training circuit lifting we do. It falls into the category of "Tabata" training. This training is the concept that by doing high level anaerobic activities continually, it will increase your aerobic levels faster than doing standard and common place aerobic training. Anyone that has run distance in high school knows that they will do 400 meter, 800 meter, and even mile repeats. Every now and then, they will do 200 repeats. But most runs are simply long slow runs. According to studies by Japanese scientists, these bike sprints 3 times a week increased aerobic capacity by a greater amount over a two week study than a control group that ran 75 minutes a day over the same period of time. Ergo, I will do my bike sprints and wind sprints and hill sprints.
