Physical fitness is
defined as “a set of attributes that people have or achieve that relates to the ability to perform physical activity” (USDHHS, 1996). In other words, it is more than being able to run a long distance or lift a lot of weight at the gym. Being fit is not defined only by what kind of activity you do, how long you do it, or at what level of intensity. While these are important measures of fitness, they only address single areas. Overall fitness is made up of five main components: In order to assess your level of fitness, look at all five components together. What
is “cardiorespiratory endurance (cardiorespiratory fitness)?” Cardiorespiratory endurance is the ability of the body’s circulatory and respiratory systems to supply fuel during sustained physical activity (USDHHS, 1996 as adapted from Corbin & Lindsey, 1994). To improve your cardiorespiratory endurance, try activities that keep your heart rate elevated at a safe level for a sustained length of time such as walking, swimming, or bicycling. The activity you choose does not have
to be strenuous to improve your cardiorespiratory endurance. Start slowly with an activity you enjoy, and gradually work up to a more intense pace. What is “muscular strength?” Muscular strength is the ability of the muscle to exert force during an activity (USDHHS, 1996 as adapted from Wilmore & Costill, 1994). The key to making your muscles stronger is working them against resistance, whether that be from weights or gravity. If you want
to gain muscle strength, try exercises such as lifting weights or rapidly taking the stairs. What is “muscular endurance?” Muscular endurance is the ability of the muscle to continue to perform without fatigue (USDHHS, 1996 as adapted from Wilmore & Costill, 1994). To improve your muscle endurance, try cardiorespiratory activities such as walking, jogging, bicycling, or dancing. What is “body
composition?” Body composition refers to the relative amount of muscle, fat, bone, and other vital parts of the body (USDHHS, 1996 as adapted from Corbin and Lindsey, 1994). A person’s total body weight (what you see on the bathroom scale) may not change over time. But the bathroom scale does not assess how much of that body weight is fat and how much is lean mass (muscle, bone, tendons, and ligaments). Body composition is important to consider for health and managing your
weight! What is “flexibility?” Flexibility is the range of motion around a joint (USDHHS, 1996 as adapted from Wilmore & Costill, 1994). Good flexibility in the joints can help prevent injuries through all stages of life. If you want to improve your flexibility, try activities that lengthen the muscles such as swimming or a basic stretching program. References U.S. Department of Health and Human Services.

Muscular endurance refers to how long muscles can sustain exercise. Improving muscular endurance can help enhance overall health and fitness. This article explores the benefits of muscular endurance, the best training routines to enhance it, and how people can adapt these techniques into common exercises. We will also look at tips to prevent injury during training and how to design an exercise program that could lead to long-term performance and health benefits. Muscular endurance is the ability to continue contracting a muscle, or group of muscles, against resistance, such as weights or body weight, over a period of time. Increasing the performance of these muscles means they can continue to contract and work against these forces. Greater muscular endurance allows a person to complete more repetitions of an exercise, for example, pushups or squats. According to the American Council on Exercise (ACE), the benefits of muscle endurance include:
Muscular endurance tests measure how many repetitions of a movement people can do before the muscles reach a state of fatigue and cannot continue the exercise. Many tests focus on measuring upper and lower body muscle endurance by measuring how many pushups, squats, or situps people can achieve. A person can work with fitness instructors to measure muscular endurance or record how many repetitions of a particular exercise they can perform before reaching the fatigue state. To increase muscular endurance, ACE recommend a combination of lower and upper body exercises, with strengthening exercises to target the whole body. Moderate resistance training, with short intervals in between for rest, creates short bursts of tension to build strength. Circuit or high-intensity interval training (HIIT) can be a suitable way to combine cardio and strength training into one workout. Unless a person’s fitness goals involve training for a particular endurance-based sport, training for muscular endurance alone may not be the most appropriate strategy. The best exercise programs mix strength and muscular endurance training. Some evidence also suggests that exercise programs that people find enjoyable may be more likely to generate long-term benefits, as they may be more likely to stick with them. A 2015 study comparing HIIT and steady-state training notes: “Variety in the type of exercise is as important as the type of exercise. Particularly considering that the health benefits of exercise have to be viewed in the context of the likelihood that exercise is continued for several years, not just the weeks of a controlled study.” When training to improve muscular endurance, what matters most is not the type of exercise, but how people design their workout. People should take into consideration the following when tailoring a workout to boost muscular endurance:
According to the National Strength and Conditioning Association, individuals training for muscular endurance should aim to complete three or more sets of 15 or more exercise reps with a load that is 50% or less of their one rep max (RM). A person’s one rep max is the maximum load with which a person can complete one repetition of an exercise. For example, a person may wish to use the leg press machine at the gym to build endurance in the legs. If they have an RM of 300 pounds (lbs), they should aim to perform 2–4 sets of 15 or more reps with a load of 150lbs or less, with brief rest periods between sets. As their muscular endurance for this exercise increases, they may wish to make the exercise more challenging by reducing rest times between sets, or increasing the reps per set, rather than increasing the load weight. A person can apply the same principle of high rep and set volume, low–moderate load, and short rest periods to any exercise, such as bench presses, dumbbell curls, pushups, or squats. People can choose exercises that suit their preferences and are challenging yet enjoyable enough to sustain training. Example exercisesAs we have already mentioned, there are no specific exercises that are better for training muscular endurance than others. The design of a training program makes it suitable for endurance training. However, ACE recommend the following exercises for building muscle endurance, which a person can perform at home without equipment: PushupShare on PinterestA pushup works the triceps, chest, and shoulder muscles.
A person can also work the tricep muscles more by placing their hands close together and turn them inward, so the fingers and thumbs form a diamond shape. To make the exercise easier, a person can place their hands on a bench or other stable, raised surface. People can also modify a push up by placing the knees on the floor to make it easier, or lift one leg off the floor to make it more difficult. SquatShare on PinterestA squat works the glutes, calves, quads, and core muscles.
Abdominal crunchShare on PinterestAn abdominal crunch works the abdominal muscles:
Pike crunchShare on PinterestAnother example of an abdominal crunch is the pike crunch:
A person can also hold a stability ball between their ankles during this exercise. LungeShare on PinterestA lunge works the abs, buttocks, hips, and thighs:
PlankShare on PinterestA plank works the core and back muscles.
A person can modify this exercise by resting on the forearms instead of the palms if they find it challenging to hold the plank position with straight arms. Tips to prevent injury during a workout include:
Muscular endurance is a muscle’s ability to continue contracting against resistance over a period of time. People can improve their muscular endurance with strength and cardiovascular training. What is the ability of muscle to exert a force during an activity such as lifting?Muscular Strength: the ability of the muscles to exert a force. The maximum amount of force that a muscle can generate in a single effort. Muscular strength in the upper body is tested by the maximum bench press and the lower body by the maximum leg press.
What is the ability of the muscles to exert a force during an activity such as lifting weights * 1 point aerobic exercise fitness exercise muscular strength power strength?Muscular endurance refers to the ability of a given muscle to exert force, consistently and repetitively, over a period of time ( 1 ).
What is the ability of the muscles to exert a force during an activity such as lifting weights exercise aerobic exercise b muscle strength C?Muscular strength is the ability to exert maximal force in one single contraction, such as lifting a weight that you could lift only once before needing a short break. Muscular power refers to a great force production over a short period of time, such as in fast leg kicks and explosive jumping.
Is the ability of a muscle or a group of muscles to exert force for a brief period of time?3. Muscular Strength & Endurance - The ability of a muscle or group of muscles to exert force for a brief period of time (lifting weights will improve muscular strength) and sustain repeated contractions (doing 1 minute of sit-ups or rowing for several minutes will increase muscular endurance).
