JKConditioning T-shirtUnstable surface training has become a common sight in the strength and conditioning realm. With the popular concept of core stability, you see more and more runners training on exercise balls, Bosu balance trainers and balance discs. Runners often mistakenly believe that this type of training will incorporate greater core activation while simultaneously developing strength. Unstable-surface training has been used successfully to rehabilitate injuries, such as the common ankle sprain, but does this type of training also benefit the healthy runner?

Stable vs. Unstable

 
Runners who strength train using a combination of resistance training, core stability exercises and plyometrics (jumps) have shown improvements in running economy, race performance and a reduced injury risk.

But not all exercises are equal. Free weight exercises performed on a stable surface rather than an unstable one appear to be more transferable to athletic performance, as trunk activation in stability ball exercises may not provide enough stimulus to increase muscular strength. One study found that after six weeks of stability ball training, subjects’ core stability improved, but running performance – as measured by V02 Max, velocity at V02 Max and running economy – showed no statistically significant changes. Other studies have shown that leg exercises performed on unstable surfaces lead to a reduction in force output, rate of force development and range of motion. In terms of stimulating strength gains, there doesn’t seem to be a benefit for a healthy runner to perform resistance exercises on unstable surfaces.

When to Wobble

 
If you’re suffering a lower limb injury, strength training on an unstable surface can help. But if you’re healthy, focus primarily on free weight exercises and plyometric drills to develop strength, power and core stability. To further reduce injury risk, add in balance board exercises to your existing strength-training program, but the focus should be on stable-surface multi-joint exercises that work multiple muscle groups. You can challenge core stability by holding one dumbbell on your shoulder instead of holding two to at your sides while you lunge.

I originally chose JKC to help me rehab following back surgery. JKC was the first gym where a trainer took the time to help me identify my goals and tailor my workouts to achieve them in a safe and doable manner. 🏋🏼 Jon & Thomas are both highly professional and knowledgeable. 👨🏼‍🎓 With their guidance and informative explanations 🗣 they have enabled me to reach my ever evolving goals.

Nutritional Coaching by Julia Howard

From my initial consult with Julia, she was professional and knowledgeable as both a Registered Holistic Nutritionist and athlete. She was interested in my nutrition and fitness goals and the development of a plan that would set me up for success.

Julia designed weekly meal plans that were complete with recipes and shopping lists. The food choices were nutritious, easy to prepare, and ensured that I felt well nourished and energized throughout my training and non-training days. Not only do I feel leaner and more fit, but I have more energy and I feel much more in tune with my body and food choices. Julia really helped me put everything in place so I can continue this process going forward- I cannot thank her enough!

I saw an article in Men’s Journal that quoted Jon in about 2018 while traveling and was impressed that someone in St. John’s made that international magazine.  Jon spoke about an exercise called the Farmer’s Walk and I started working that into my routine at the YMCA. I tore that article out of the magazine and kept it, meaning to make contact, but got busy. Then I had lunch with an old friend Bruce Dyke. I hadn’t seen Bruce for a while and I remarked that he looked super healthy and fit. He told me about his, and his son Cas’, experience at JKC and then I remembered the Men’s Journal article! No coincidences!

The experience is unique on many levels – great people, camaraderie, passion, purpose, and dedication. Jon and Thomas are attentive, precise and understanding.  Their teaching has unlocked a new perspective for me with what our bodies are capable of. I still appreciate the YMCA, wonderful place, but I can’t imagine working out without Jon and Thomas now.
