Hi all,
Sorry, When I went to post my question, part of it cut off, and I didn't have the time to fix it before needing to leave for a few hours.
What I've been told by local riders here is that HIIT usually involves riding at a very difficult pace for 30-90 seconds followed by a rest for double that time. Once you become more fit, the intensity split will become 50-50. This recovery is called excess post-exercise oxygen consumption or EPOC, which means that there is a substantially large increase of oxygen intake to replenish the oxygen deficiency that you just experienced. This is important because you will actually be burning calories long after the workout is over.
After a Tibial plateau fracture in Feb 2015, it took me approx 8 months before I could walk without a cane, and another 6 months before I could ride somewhat comfortably on a recumbent trainer, and I'd put on 15 pounds in that time. Last August, after getting the hardware removed from my leg, I was finally allowed to get back on my Freerider and ride, what a pleasure. But winter comes early here in Montreal, and I had to get back indoors in late October. I worked on the trainer in my mother in law's apartment complex until the end of the year.
I took a membership at my local gym in January, and rode the recumbent trainer about 5 times a week until April working to get my strength and endurance back. Then, I rode my Freerider and really was able to push a lot harder, getting close to my past form. But in that time , until July, I only was able to lose 3 pounds.
I checked with my doctor about HIIT training, He had me do stress test, it was good, and he gave me the go ahead. In the 2 months since, I've lost another 6 pounds, and my strength and VO2 Max have increased quite a bit. I find that the hills I ride outside of Montreal (Quite flat on the island) are much easier to climb than they were before my accident.
I just now checked the Keto diet, and will try to incorporate in my diet, I'd like to lose another 15-20 pounds, and it looks like it's quite manageable. If only I can discipline myself to cut out sugar !
Thanks for the info,
Denis
