Fitness Myth Busted: Core Stability and the Bosu

October 23, 2009

All across the globe, personal trainers push their clients up onto BOSU balls with claims that it increases core muscle activity.
And while I personally think that the only reason trainers’ use the BOSU is to make their clients look silly…

…I always wondered what would happen if the BOSU got dragged into a university lab and put through it’s paces.
Well, back in March of this year, researchers from Eastern Illinois University did just that.
The Study
PURPOSE: To compare core muscle activity during resistance exercises performed on stable ground vs. the BOSU Balance Trainer.
METHODS: Twelve trained men performed the back squat, dead lift, overhead press, and bicep curl lifts. Each lift was performed under three separate conditions:

50% of 1 RM (rep max or max possible lift) while standing on solid ground,

Warrior Fit Testimonials

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.
