Jean brought up a very interesting point today, she said that she always took it that you needed to work for at least 20 minutes before she starting burning fat. In theory, she is right and your body will start burning it’s carbohydrate and simple sugars first, then after the 20 minutes stage depending on energy levels in the body, fat can then be used as a fuel source so that does work-in a perfect world.
What happens if nothing is going to plan that day, we need a quick workout and we can only fit in a 15 minute run, is it worth it? We can only do 20 press ups, 20 arm dips. 20 squats, and 70 squat thrusts, is it worth it? What if you can only get a 10 minute walk in with the dog as you have to go back to work, is it worth going even you put in a light jog? Is it worth going for 15 minute bike ride when we usually do 45 mins? Will we burn fat if we do any of these things?
The answer must be a resounding “yes”! Of course, we would spend a little more time warming up and getting into the workout, it’s not good to rush in and go 200% all the time! What i am saying is that any exercise is good, and i have had some of my best workouts in under 10 mins. Breaking 9 minutes for the first time whilst doing 2500 metres on a rowing machine nearly half killed me! Usain bolt does his best workouts in under 10 seconds! What about the guys and girls who do the run up the stairs every february in the empire state building in new york? There are 1575 stairs and the women’s record is 13 minutes 12 seconds, the men’s rec0rd is 9 minutes and thirty three seconds.
Do you think that any of these workouts/events burnt any body fat or not? Of course they did and often pushed our bodies to new levels of achievement and conditioning.
The key is you are pressed for time is to raise the intensity to suit the workout. For instance, if you are used to running for 30 minutes on a flat surface and that gives you an effort of 8 out of 10 then great. Do make a workout of 15 minutes much more intense, incorporate hills or interval training, do some sprints with minimal rest, in fact do anything that makes it harder and really try and take rest out of the equation.
P.S. To clear up my home workouts post yesterday, my example workout was exactly that, an example. For instance if your best test on your own was 20 press ups, 30 arm dips, 60 squat thrusts etc, your circuit you do 3 times should be half of that. Therefore, it would be 10 press ups, 15 arm dips and 30 squat thrusts. Effectively, you are halving your personal best totals but doing them a total of 3 times instead of once. This will make a very effective workout indeed. Any problems let me know.
