The Importance of Strength Training Julia Pilliar, BKin, CPT Aerobic activities such as jogging, swimming, and cycling are often believed to be the most important forms of exercise. However, cardiovascular conditioning is only one of four components fitness, (cardiovascular conditioning, muscular conditioning, body composition, flexibility) all of which must be maintained for optimal health and well-being. Muscular conditioning includes ENDURANCE (the ability to contract a muscle repeatedly over a prolonged period of time (e.g. holding the plank, doing as many push-ups or squats as you can), and STRENGTH (a muscle’s ability to generate force in a short time period, as in doing a weighted squat, a bicep curl, or picking up a heavy object). Muscular endurance is critical to maintain good posture and prevent repetitive injuries, and muscular strength makes activities of daily living such as grocery shopping and gardening feel easier Muscle is more metabolically active (uses more calories per hour) than fat, thus increasing muscle mass can help to raise your metabolism contributing to a healthy body composition. Strength training also helps to maintain healthy bones and prevent osteopenia and osteoporosis. Any activity that challenges muscles more than daily activities do contributes to improvements in muscular conditioning. This may include a challenging yoga or pilates class, a body sculpting class, or working with weights, tubing, or doing calisthenics (body weight exercises).. The Canadian Society of Exercise Physiology recommends that healthy adults engage in strength training at least 1 time per week to maintain muscles, and 2 or 3 sessions per week to improve. Just remember, give yourself at least a day of rest in between exercise sessions as this time is needed for muscle repair and growth.
