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 started at JKC in January of 2014 and I’m 67 years old. When I had my Initial Assessment, I knew – almost immediately – that Jon knew what he was doing and what he was talking about. I was overweight, out of shape, and in serious need of someone, like Jon, who could get me back on a fitness/conditioning routine that suited me, my age, my less than acceptable physical condition, my sometimes intermittent RA, and my need for a structured, consistent and yet flexible training and conditioning program that would work for me.

Fundamentally, if I made a choice at all with respect to JKC – it was to continue to come back each week. I have not been in a lot of gyms. To be honest, they used to intimidate me. What makes JKC different is their approach to each and every one of their clients. Jon and Thomas – and now Craig – tailor each training regime to the particular needs of each client. That ensures that the training regime will suit each client upon the start of training and changes as the client improves. It adjusts for any physical setbacks such as injuries and it adjusts for success. It is just that simple.

It is also the consistent encouragement that comes from Jon, Thomas and Craig. That voice that comes to you while you are in the middle of a particularly difficult set – rear-foot elevated split squats comes to mind immediately – that says “good job” or “keep it up” or “just a couple more reps.” To know, in that moment, that you are not alone and the trainer is paying attention to what you are doing. That is priceless for me.

I’m 40 years old & started training at JKC in 2015. The gym I was working out at closed and my husband recommended JKC. JKC meets you where you are in your fitness journey and tailors the work to help achieve your goals. I’ve trained with Jon & Thomas pre pregnancy, while pregnant and now post baby and they have helped me enormously to stay fit through all life phases.

I joke with the guys often that I’ve seen no change in my fitness level since joining the gym, but the reality is I’m in far better shape at 40 than I ever was at 30 thanks to them.

I came to JKC through recommendations from my peers from lululemon. As a current ambassador, I’ve been introduced to legacy ambassadors, like Jon, and I knew a bunch of other people from the store were working out here so I wanted to give it a go. I often dread lower body workouts so I started coming here to do legs. I’ve had such great progress that I now come twice a week— and, I no longer hate leg day!

I’ve never experienced this sort of hybrid between group workouts and personalized service. Many group strength training services offer a sort of one-size-fits-all workout for the general population, which has never been of interest to me, because I want my workout tailored to my needs! I LOVE that you can be in a group setting while doing your own personal program; I love the camaraderie and community at JKC, and, I’ve seen incredible results thus far! Jon is always so attuned to what I need.

I’m 43 and started at JKC just over a year ago. I started at JKC because of multiple recommendations from existing clients. There are 2 main elements that distinguish JKC for me. Firstly the sense of community. I’ve been to multiple gyms in multiple cities/countries, you just  can not manufacture the sense of community and support you get from other gym goers and the team. It’s very motivating and happy to say I’ve made some friends at JKC.

The other major distinguishing factor for JKC is the expertise and passion of the team. Jon, Thomas and Craig craft highly personalized programs based on my fitness goals and know how to push me best without being pushy. They pay close attention to ensuring my form is solid before encouraging me to take on more weight for the exercise. Plain and simple they love what they do and it shows.

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.
