After the positive reception to part one of this blog post, we thought it would be a good idea to introduce part two. Below you will find some good information in a rapid-fire format. Without further ado, let’s get started!

Stay Out Late? Lift Less.

Ever tried to workout hard the day after a late night of partying? Probably wasn’t a fun experience, was it? Thanks to a research team from Brazil, we now know that this isn’t a good idea. In their experiment, participants were given alcohol and forced to stay up late. Lo and behold, when they were tested the next morning, their performance suffered! [1] So, if you still want to workout the day after a big night, try to keep it light.

They See Me Rollin’

Have you ever been foam rolling and wondered how much pressure you should be applying? I know I have. Well, it turns out, to help increase your range of motion (RoM) it really doesn’t matter. A research team right here in St. John’s examined three different levels of applied roller force and found neither one to be better than the other. Who would have thought? So, maybe don’t worry too much about going hard with the foam roller and just do it. [2]

Play Late, Sleep Poorly

To all those reading this, if you play a game of your favourite sport at night, how would you rate your sleep quality that night? For me, it takes a long time to unwind for bed after being highly stimulated for an extended period. It turns out; even professionals are affected by evening games. In a study of professional soccer players, 90% of those who played in games starting after 6:00pm reported sleep disturbances.  So, if you are hoping for a good night’s rest, maybe rethink that 10pm hockey game.

Is It The Shoes?

When it comes to deadlifting, what do you prefer shoes or no shoes? Personally I prefer a nice flat shoe with a minimal heel. Well, it turns out that it may not even matter. In a study examining shod (with shoes) versus barefoot deadlifting, researchers from Australia found that there was no difference in rate of force development or peak vertical force between the two conditions.

Better Grip, Better Golf?

Looking for a quick way to improve your golf performance? Researchers from the United States may have just what you are interested in. They tested the effects of training using fat gripz (a rubber attachment that increases the diameter of a barbell) on ball speed, driving distance, and driving carry. Interestingly, training with fat gripz increased these parameters significantly more than a group who did not train with fat gripz. [5]

That’s a wrap! I hope you enjoyed this look at some of the research coming from the strength and conditioning world. As before, if any of this piqued your interest, I have included the links to the studies cited in the article below.

I chose JKC because I was looking for something different. I’ve seen and done the trendy workout programs before, I was looking for something that I knew I could see myself still doing a year from now! JKC has a lot of clients that have been going for years. That was a huge motivator for me! The small group coaching sessions are great and I really enjoy the format. It’s nice having 2-4 people working-out with you during your session. The camaraderie is great, everyone is very upbeat and positive – zero gym judgment!

Personal Strength Training by Jon-Erik Kawamoto

Have to thank both Jon and Thomas for their help with my conditioning this past year. After a major injury in 2020, I tried everything. My foot doctor (Dr. D. Sutton) said there was something missing and recommended Conditioning. I then found JKConditioning and it definitely worked for me. Today September 8, 2024 I completed a Half Marathon in 1 hour and 42 minutes and came First in my age group.
Thank you JKConditioning!!!

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.

JKC was recommended by a previous trainer who followed Jon online. He thought Jon’s approach to training was excellent. JKC employs well educated trainers who are very particular about technique and form. I have never injured myself because the trainers know what they are doing. They can always answer any questions I ask about my training. As well the trainers are friendly contributing to a relaxed and friendly atmosphere at the gym.

I started training at JKC in 2016 because I had built up a number of muscle imbalances from old injuries and activities like rock climbing which had led to some really bad posture and mobility issues. On top of that some friends had convinced me to sign up for a half-ironman. Working with Jon and Thomas was a way to pull my body back into alignment and make sure it wouldn’t fall apart during my race. The staff at JKC pride themselves on continuously advancing their knowledge, which leads to new and inventive way to address problems, old and new. I got my Dad to start training here and recommended JKC to all looking to improve their strength and fitness.
