Les Mills BODYPUMP 87 Launch & the importance of strength training

10/30/2013

Launching a new BODYPUMP workout is always an exciting time, and the launch of 87 certainly did not disappoint. This release is one of my favorite BODYPUMP workouts yet - the music is great and the back and lunge tracks are KILLER! My favorite tracks are squats & biceps for the music and back & lunges for the challenge. This year, the launch coincided with our Freaky Fitness Fest at the gym - a full day of free group fitness classes, prizes and even a dance class to learn the moves from the Thriller video. It was double trouble for me - I started my day team-teaching the 7:30am class with Jackie, and finished things up at the 6:30pm class with Alex and Carrie.

Why is it important to strength train?

It is important to understand the basics of strength training and why you should incorporate this activity into your training program. Muscle mass naturally diminishes with age. "If you don't do anything to replace the lean muscle you lose, you'll increase the percentage of fat in your body," says Edward R. Laskowski, MD, a physical medicine and rehabilitation specialist at Mayo Clinic and co-director of the Mayo Clinic Sports Medicine Center. "But strength training can help you preserve and enhance your muscle mass — at any age." It's the good old "use it or lose it" phenomena. The lean muscle mass that we all work so hard for decreases with age. If we don't add strength training to our routine then it will turn into fat. Below are some specific benefits of strength training.

Develop strong bones. By stressing your bones, strength training increases bone density, resulting in stronger bones and reduced risk of osteoporosis. One of the best ways you can control bone loss as you age is to add strength training into your workout plan.
Control your weight. Strength training will not only make you strong, but will also help with managing your weight. As you gain muscle, your body begins to burn calories more efficiently because your body works harder to maintain muscle over fat. The more toned your muscles are, the easier it is to control your weight. Controlling your weight can also improves your quality of life as you gaining body confidence. In a specific study where BODYPUMP™ was used for strength training, An average of 483.1 (males) and 338.9 (females) calories can be burned during a BODYPUMP™ session. This equates to 8.4 (males) and 5.9 (females) calories per minute. An additional 10% of calories have been shown to be burned after the cessation of a BODYPUMP™ session, due to Excess Post-Exercise Oxygen Consumption (EPOC). Who doesn't want to burn more calories?
Boost your stamina. As you get stronger, you won't fatigue as easily. Building muscle also contributes to better balance, posture and functional fitness.
Manage chronic conditions. Strength training can reduce the signs and symptoms of many chronic conditions, including back pain, arthritis, obesity, heart disease and diabetes. It not only builds muscle, but increases the strength of connective tissue, muscles, and tendons. This leads to improved motor performance and decreased injury risk. Strong muscles, tendons and ligament build up in the joint and back areas making these areas less likely to give way under stress.
Muscle tone. The conditioning effect will result in firmer and better-defined muscles.
Improved aerobic fitness. In the same study as mentioned above, it was found that during a BODYPUMP™ session the mean oxygen consumption was 21.5 ml/kg/min (males) and 19.0 ml/kg/min (females), with an average intensity of 41.6% VO2 max (males) and 39.8% VO2 max (females) observed. Males spent an average of 11.6 minutes and 3.2 minutes, and females, 8.0 minutes and 0.6 minutes, above 50% VO2 max and 70% VO2 max, respectively, during the same BODYPUMP™ session. The average heart rate during a BODYPUMP™ session has been shown to reach 138.2 beats per minute (males) and 132.6 beats per minute (females). Males spend an average of 37.4 minutes, and females 40.2 minutes, above 70% of maximum heart rate during a BODYPUMP™ session.
