You want your muscles to become stronger, but you must also consider the range of motion (ROM), you’ll be using for a particular exercise. It is crucial that you consider this if your training will be able to translate well into everyday life. You could injure yourself if you don’t use your full range of motion when performing exercises. Exercises that include full range of motion will help you lose more weight and build strength so you can do everyday activities.
While training your body in a narrower or more limited range may make it look more attractive (and help you be more confident), it does not prepare your body for all the tasks you will face every day. You may also endanger your health if you train with a limited range of motion. Clients should use the full range of motion in all exercises. You can also be considered if you are unable to exercise due to a past injury, structural discrepancies or just plain not being able move freely. You will then be micro-progressed, moving from lighter to more heavy loads until you reach your own natural range.
My pet peeve is when clients try to sacrifice their body for speed or weight. Clients who try to lose weight or speed up an exercise will often shorten their forms and compromise the benefits of the exercise. This will result in them wasting time and effort. Give yourself permission to use all ranges of motion. Even if this means that you must reduce your weight. In no time, your strength will increase across the entire range. You will now have an active body, no matter what activity you do.
