BodyAttack

Last updated

BodyAttack is a commercial group-fitness sports inspired cardio workout program including some sports-derived movements, aimed primarily at developing cardiovascular fitness. The program is created and distributed by Les Mills International. [1] There is a release with new music and movements every three months. [2] In the UK, it is offered at around 1,300 health and fitness facilities, approximately one fifth of such facilities in the country. [3] It consists of a standardized class that is either 55, 45 or 30 minutes in length, led by a certified instructor who leads participants through various exercises to a contemporary music soundtrack. Like BodyPump and other Les Mills programs, the movements, exercises and music are standardized for all instructors. [4] The aim is to develop numerous domains of physical fitness, particularly cardiovascular fitness and stamina.

Structure

The structure of a BodyAttack class never changes, although various tracks may be skipped to shorten the workout to either a 45 or 30 minute workout.

The class is divided into two blocks of work, each of which has one cardio peak. Each block consists of several tracks, where each track is a routine set to a specific song. The songs and routines are changed periodically, but the exercise focus of each track remains consistent. The first block starts with a warm up and peaks with a plyometrics track. The second block starts with circular running and peaks with a power track. The routines are designed with the goal of maximizing participants' heart rates during the two peak tracks, particularly during the power track.

The music and routines for each track are changed every quarter-year. Each new set of music and routines is numbered sequentially, with past track lists being referred to by number. For example, the track list in use for the first quarter of 2019 is referred to as "BodyAttack 109". [5]

Formats

A full 55 minute class consists of 11 tracks in a fixed order. Instructors are required use one of the formats provided by Les Mills and may not change the order or format of tracks.

55 Minute Format

Before BodyAttack 87, track 5 was focused on upper body strength and conditioning and there was an additional track between tracks 9 and 10 for lower body strength and conditioning. [6]

45 Minute Format

A shorter runtime is achieved by skipping some tracks from the full 55 minute format. There are two options for this format:

30 Minute Format

The shortest format includes only tracks 1, 2, 4, 7, 9, and a modified version of track 5. Tracks 3 (aerobics), 6 (running), 8 (interval), 10 (core), and 11 (cooldown) are skipped.

Research

Few published studies have investigated the BodyAttack program scientifically. One study investigated the energy expenditure and oxygen consumption of three male and three female participants (mostly instructors) during a typical 55-minute BodyAttack class, undertaken in a controlled laboratory setting. Average energy expenditure was 660kcal for the male participants and 602kcal for the female participants. [7]

Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness. It is usually performed to music and may be practiced in a group setting led by an instructor. With the goal of preventing illness and promoting physical fitness, practitioners perform various routines. Formal aerobics classes are divided into different levels of intensity and complexity and will have five components: warm-up, cardiovascular conditioning, muscular strength and conditioning, cool-down and stretching and flexibility. Aerobics classes may allow participants to select their level of participation according to their fitness level. Many gyms offer different types of aerobic classes. Each class is designed for a certain level of experience and taught by a certified instructor with a specialty area related to their particular class.

<span class="mw-page-title-main">Aerobic exercise</span> Low to high intensity physical exercise

Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring oxygen", and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. Examples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking.

<span class="mw-page-title-main">Physical fitness</span> State of health and well-being

Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan.

Indoor cycling, often called spinning, is a form of exercise with classes focusing on endurance, strength, intervals, high intensity and recovery, and involves using a special stationary exercise bicycle with a weighted flywheel in a classroom setting. When people took cycling indoors in the late 19th century, whether for reasons of weather or convenience, technology created faster, more compact and efficient machines over time. The first iterations of the stationary bike ranged from strange contraptions like the Gymnasticon to regular bicycles placed atop rollers.

Fartlek is a middle- and long-distance runner's training approach developed in the late 1930s by Swedish Olympian Gösta Holmér. It has been described as a "relatively unscientific blending" of continuous training, with its steady pace of moderate-high intensity aerobic intensity, and interval training, with its "spacing of [more intense] exercise and rest intervals". Simply stated, in its widely adapted contemporary forms, fartlek training is alternating periods of faster and slower running, often over natural terrain, including both "level and hilly terrain".

<span class="mw-page-title-main">High-intensity interval training</span> Exercise strategy

High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity, because the body significantly recruits anaerobic energy systems. The method thereby relies on "the anaerobic energy releasing system almost maximally".

<span class="mw-page-title-main">Step aerobics</span> Form of aerobic exercise

Step aerobics, also known as bench aerobics and step training, is a form of aerobic exercise that involves stepping on and off a small platform.

Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or break periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity. Varying the intensity of effort exercises the heart muscle, providing a cardiovascular workout, improving aerobic capacity and permitting the person to exercise for longer and/or at more intense levels.

Circuit training is a form of body conditioning that involves endurance training, resistance training, high-intensity aerobics, and exercises performed in a circuit, similar to high-intensity interval training. It targets strength building and muscular endurance. An exercise "circuit" is one completion of all set exercises in the program. When one circuit is completed, one begins the first exercise again for the next circuit. Traditionally, the time between exercises in circuit training is short and often with rapid movement to the next exercise.

<span class="mw-page-title-main">Barre (exercise)</span> Form of physical exercise

Barre is a form of physical exercise, usually conducted in group classes in gyms or specialty studios. It is distinguished from other group fitness activities by its use of the ballet barre and its incorporation of movements derived from ballet. These classical dance movements and positions are combined with those drawn from yoga and pilates, and other equipment is sometimes used in addition to the barre, such as resistance bands, yoga straps, exercise balls and hand weights. Barre classes typically focus on small, pulsing movements with emphasis on form, alignment and core engagement. Participants hold their bodies still while contracting specific, targeted sets of muscles in isometric exercises. Repetitions tend to be high, range-of-motion small, and weights, when used, light. Barre classes focus on the lower body and core, developing strength and flexibility from the ankles up though the calves, knees, thighs, glutes and abdominals. Holding muscles in contraction for extended periods frequently leads to them shaking as they fatigue. This is particularly true of thighs, as the quadriceps tire.
