Time of Day and Workout Quality: Is there a Link?

The alarm clock rings. “Oh God”, you think, “How can I possibly train this early in the morning? I just know this will be a terrible workout, I’ll be so weak”. Ring any bells? Or perhaps you get home from work and think that after all day you can’t possibly perform to your potential during your evening workout. While either of these scenarios may be far too familiar to you, it’s worth considering the science that has been conducted on circadian rhythms (your body’s natural clock) before you put off that New Year’s resolution for another year.

The Science:

In one of only a handful of studies examining the topic, researchers at the University of Rhode Island examined the influence that time of day at which a workout occurred had on the mental readiness, power, and force output (But not swoliness!?) of college aged men. These poor fellows were strength tested at four different times of day, 4:00 (ROUGH!), 10:00, 16:00, and 22:00. Interestingly enough, there were no differences in force output, power, or mental readiness between any of the test times.

The Take Home Message:

So what does this mean for you? Well if you are only able to exercise during the early morning or later in the evening than this research indicates you should achieve the same results as any other point in the day! While lack of a comfortable time to exercise may be a good excuse for many people, don’t let it be yours! This New Year’s, instead of making another excuse, make a commitment to yourself!

Personal Strength Training by Thomas King

After my children were born, I was completely out of shape. I had been active before my first pregnancy in 2008. I saw a post on social media about a charity event that was hosted at the gym. It prompted me to check out the JKC website. I was immediately impressed by the professional content and decided to give it a try. The professionally crafted and uniquely tailored work outs, as well as the sense of accountability and commitment that they foster. I have not missed a workout since joining – contrary to other experiences I have had when purchasing gym memberships. The flexibility of booking and rescheduling workouts, made easy by an online app, also contributed to my success in meeting my fitness goals.

I enjoy every session, working out with Jon, Thomas and Craig, as well as the “JKC Community”. Anytime someone achieves a personal best, I enjoy the celebration and support everyone gives each other. For me, I fondly remember achieving personal bests on bench press, chin ups and the sled push, in particular.

JKC was recommended to me by my good friend Casidhe Dyke. Cas had been training with JKC for a while, and both he and his father had seen great results from the personal training that Jon and Thomas were giving them. I was and still am primarily a triathlete and I’ve always struggled with injuries. I was talking to Cas about incorporating more strength training in my program to try and prevent injuries going forward and Cas suggested that I give JKC a try. I reached out to Jon not long after, and the rest is history! After working with Jon and Thomas for a few months, I was getting stronger, faster, and most importantly, I was staying injury-free. I ended up being able to train the whole season without significant injury and posted a personal best at Ironman Copenhagen in 2018. A big part of that was due to the strength training and coaching I received at JKC.

I had always wanted to start lifting weights and get stronger, but didn’t know where to start. I was looking not just for a gym, but for training on proper technique to prevent injury and a program designed for my specific goals. I also wanted a fun and supportive atmosphere to keep me coming back. JKC delivered on all of this and more.

Jon and Thomas have a wealth of knowledge that help their clients get the most out of their time in the gym. Programs are continuously modified to keep the workouts challenging. Even through everyone’s program is unique, you always have the coaches and other clients cheering you on and pushing you to achieve new bests.

Nutritional Coaching by Julia Howard

For the past two months I have worked with the JKC team and have never felt better! In addition to a personal fitness plan, JKC’s holistic nutritionist, Julia, worked with me and around my busy schedule to educate me on healthier food options and meal planning. I maintain a daily food log which Julia reviews and provides feedback on and we also have weekly chats to discuss my nutritional goals and potential improvement areas. Julia also helped me to identify and work around dietary constraints which have caused digestion issues for years!

Julia and the rest of the JKC family have helped me get my confidence back! I love starting my days with a good sweat and a healthy breakfast. I understand what foods make me feel my best and my body is well on its way to becoming more lean, fit and happy! I would totally recommend Julia and the entire JKC team!

I heard somewhere that achieving your health goals is determined largely by what you do in the kitchen. I am grateful to have found Julia who brought direction and accountability to this most important piece for me. Having Julia in my corner has brought me confidence and certainty that I am on my way to achieving my goals. I highly recommend her if you are serious about making a change and feeling better about your health.
