As the warm days of summer start to wind down you may be beginning to worry about how your progress in the gym will be affected by the numerous food holidays coming up: Thanksgiving, Halloween, and the nuclear bomb of eating events, Christmas, with all its parties and events.

 

Maybe you think that the best approach to combat excess weight gain while still enjoying the events is countless hours of steady state cardio, you know, long runs on the treadmill, torturous climbs on the stair master and endless cycles on the spin bike.

 

***Or, you could try a much more efficient approach***

Interval Training!

 

What is interval training?

Interval training is high intensity bursts of activity interspersed with lower intensity active rest breaks. A very simple example would be running up a long set of stairs very quickly then walking back down and repeating.

Why do interval training?

The main advantage of interval training is the short amount of time it takes to elicit excellent benefits. In fact, a recent review paper that looked at the benefits of high intensity interval training (Carrasco, 2017) found that in most cases, interval training resulted in approximately twice as much weight loss as traditional steady state training.

So how much should I be doing?

The review paper referenced above looked at eight research studies all of which used varying interval lengths and total times. Essentially, it makes little difference as long as the intensity is very high. Shoot for about 90% of your max heart rate during your high intensity interval.

How do I calculate my max heart rate?

 

Your max heart rate is based on your age. It is calculated as: 220-Age
For a 45 year old individual, their max heart rate is 220-45 = 175
Using 90% would give:175*0.90 =158
So…our hypothetical trainee would try to get their heart rate up to about 160 beats per minute during their high intensity interval

 

Making interval training work for you:

  • Aim for intervals of about 10 seconds of high intensity pace (fast running, cycling, swimming, etc) and 20 seconds of lower intensity rest (Walking, etc).
  • Try to sustain this effort for about 7-8 minutes
  • Be sure to warm-up and cool down for about 5 minutes before and after the intervals
  • If you want to increase your calorie burn, add resistance. This could involve pushing a sled :), using a resisted bike, such as a fan bike, or performing loaded carrying exercises such as farmer’s walks.

The Take Home Message

  • Interval training is a fast and effective way to experience awesome fat loss results.
  • For it to be effective though, the intervals must be very intense. You definitely should not be able to speak while doing the high intensity portion.
  • If you have any questions about how to incorporate interval training into your routine, please ask Jon and Thomas. They are happy to help!

I’m 29 and I just had my 3rd Liftiversary 🥳 at JKC. I chose to train here because of the great word on the street and the fact that at lululemon, we’re encouraged to support our local community. My day-to-day routine is very busy, and I love showing up and having to think very little about my workout. The vibes are always good, my music choice is usually accommodated, and the bys are incredibly supportive and compassionate, helping me reach my goals (even when I had a broken hand). I also get to be my weird self, and am embraced fully.

JKC is different from other gyms/fitness regimes I have tried in the past because of my level of comfort with the facility and other JKC clients and the amount of knowledge both Jon and Thomas demonstrate through personal attention to form, core development and overall strength is outstanding. JKC is by far the best training hands on attention that I’ve experienced period and I have experienced many over a lifetime of activity and playing various sports. The facility has everything you require plus, as you will learn there are many ways to use every piece of equipment and Jon and Thomas are very creative! There are many age groups and professions who attend this gym from elite athlete’s to the rest of us and the casual but focused atmosphere in the gym makes each visit interesting, friendly and challenging at all levels.

I’m 34 and started at JKC in 2015. My wife joined while I was working away in 2015 and started making amazing progress while also completing exercises I’d never perform on my own. I felt I was missing out so I signed up. JKC helps in establishing goals while also having clear direction of what to do, and how, in each session. They also measure your progress which is another means of motivation! At other gyms I wouldn’t have a clear plan and would just use whatever equipment was free, it was hard to see any results. Between setting some personal bests and making good friends its hard to identify a favorite memory.  One that does come to mind was when I hit my target goal/PB in both bench and squats in the same session, big day.

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.
