Welcome to Effective Training! By Kelly Knueppel
Did you know that the classes here at Kelly’s Fitness are designed based on the latest scientific research on fat burning? If you have tried one of these classes, you may be surprised by the intensity or you may have become sore from the weight training. Allow me to explain what we are doing and how you can successfully work up to it.
You have heard for years that you need hours and hours of low level aerobic exercise to lose weight. Thankfully, there is a more effective way to burn fat and it involves far less time! “When it comes to exercise, there is a threshold of intensity beyond which the cascades of growth hormones are released: leading to a “ripple effect” on the metabolism that forces the body to adapt…and become leaner, faster and stronger.”1 You cross this threshold by training anaerobically, which is more intense than aerobic training. There are two main ways to do this and we use them both in class. Interval training refers to a type of cardiovascular workout where you push very hard, or “burst”, and then recover and repeat rather than plod along at a steady rate. Resistance training refers to the many ways that we challenge the muscles to become stronger. We use weights, bands and bodyweight to do resistance training in class. Both intervals and weights produce the “metabolic effect” of post exercise oxygen consumption. This means that you will burn calories during the workout and then for hours after!
Several important studies show that groups trained with interval training will lose 9 times more body fat than groups doing lower level aerobic training for greater amounts of time!2
Our workouts elicit the metabolic effect through both interval training and through full body weight training. Not only does training this way burn fat faster, it turns your body into a fat burning machine because it increases muscle or lean body mass. When you increase your lean mass, you may eventually need more calories. Cardio machines show a “fat burning” heart rate zone which is low level in order to stay aerobic. This is because you do burn a greater percentage of calories from fat at low levels. Unfortunately, you must remain in this zone all day to burn as much actual fat as you would from the after burn of the metabolic effect. Even more unfortunate is the loss of lean muscle that you experience from too much aerobic cardio. When you add dieting to working out in that zone; you really eat away at your muscle so that you need fewer calories to survive. Interval training preserves and increases lean mass, ensuring that weight lost is from fat alone.
Weight training triggers the same effect with even more lasting calorie burn due to an even greater increase in lean muscle mass. “a weight training program that uses full body movements, short rest periods, and forces both mechanical and metabolic muscle failure will cause a ripple effect lasting long after exercise has ended…two studies show a 16 hour elevation for women…this is admittedly hard to swallow when one considers exercisers spend countless hours doing aerobic workouts which are largely ineffective for weight loss.”3

However, due to the anaerobic nature of resistance training, it generates greater calorie utilization during the recovery period following the exercise session. The biggest benefit of resistance training, however, is the addition of new muscle that requires more energy all day long. A pound of new muscle uses 30 to 50 calories a day for tissue maintenance, and that really adds up over a week's time.” 4
Here’s how you can prepare for interval training. You need an aerobic base that allows you to maintain 30 minutes of cardio at 60% of your maximum heart rate.5 Once you can do that; you should increase intensity rather than duration. The weight training will also prepare your body for the rigors of cardio intervals. Start with the 5 lb weights but do not stay there. Listen to your body, take breaks and give yourself 3 months of 2-3 classes per week keeping the lower heart rate before you enjoy intervals. If you don’t have a heart rate monitor, stay at a level where you can still talk. Intervals, when you are ready for them, take you above where you can still talk. The resistance training that we do will make you sore at first. Bear with it and keep coming. It should disappear after the next warm up. If you feel pain other than muscular soreness, see me.
The best news of all is that these three workouts, Monday, Wednesday and Friday are all you need for a while. It’s fine to do additional walking, biking or recreational exercise and it will help, but 2-3 doses of the metabolic effect will give you amazing results! There is more to learn regarding nutrition, but that’s another article!
See you in class, Kelly
