How Interval Training Works – Lactic Acid, Oxygen Debt, and Recovery

September 10, 2009

I talk about different forms of interval training and circuit training on this blog on a regular basis. I tend to shy away from discussing things like lactic acid and oxygen debt, because these are "zone out" terms. Many people tend to skim when blogs begin to read like Biology text-books. I want to explain how intervals work and go into more details, without making this a mind-numbing technical article.

Why Do We Push, Then Rest A Little, Then Push Hard Again?

Since intense exercise burns a lot of calories, why don't we just push hard the whole time instead of mixing in periods of active rest? I mean…if you have 15 minutes to do some form of training aimed at fat loss, why not spend […]

First, I want to say thank you for convincing me to do Tabata! I was struggling to lose weight and Finally I found something that helped! I really appreciate your coaching! - Craig T.

Ever since I was convinced to do Tabata I have seen huge results, I lost 6 pounds and gained energy in the first 3 weeks. I have been working out for 3 months before I decided to do Tabata and I struggled to lose weight. At first I thought "How am I losing weight by bringing my heart rate up then cooling down then bringing it up again?" I don’t know how it works but it does! Thank you!! - Theresa F.

The first day of Tabata, I wondered WHAT AM I DOING - I AM 56 !! Five weeks later I knew that it was what I needed. I learned that I could push myself well beyond my comfort zone and feel good later. I have a marked improvement in physical as well as emotional endurance. - Lyn C.

When I was first told about Tabata I was very excited from the word go, however that excitement stemmed from the fact that I had no clue what it meant. I missed the first week of class b/c I was traveling for work so when I came in during the 2nd week I had some making it up to do. It was hard at first b/c my body wasn't used to working out at such a fast pace, but once I got into a rhythm I started to feel very good. These classes are no joke. If you stick with it you will leave there feeling stronger, healthier and overall better about yourself and what you've accomplished. I would recommend these classes to anyone. Darrin is a great trainer and he'll keep you going with his energy. - Jami L.
