Hip Flexor Stretches

Typical workouts often lack stretching exercises in the routine, especially for the Hip Flexor. Some of the most effective hip flexor stretching exercises involves :

Supine Stretch

Position yourself in a flat back or supine posture. Bend and pull one leg onto your chest while extending the other leg at the same time in a straight direction before you and ultimately resting it over the floor. This will stretch the hip flexor muscles. One you hug a leg to your chest, you should hold the posture for around 20 seconds.

Relaxation Stretch

Lie flat on your back. Pull your knees towards yourself while keeping both feet over the ground and around 15 inches away from your buttocks. Keep your hands and arms relaxed beside yourself or on your stomach.

Once you have achieved this position, pull your bones towards the ground. You will start noticing that the distribution of weight will increase all through your body when the hip flexor muscles begin to release.

Seated Hip Flexor Stretch

This is a more intense type of hip flexor stretch and can relax extreme tightness of your muscles. Kneel down over a mat or any soft surface. From this posture, slowly lower down your buttocks in the direction of your heels. Start sliding it out before you while you are keeping the right leg in a bent posture. Start making the left leg straight behind you and ultimately extending it out in a straight direction. Let it rest over the ground with the knee pointing downwards.

Use your arms to support the weight of your body. Bend forward and shift over your right hip into a seated posture. Hold this posture for 20 seconds or more. Switch legs.

Prone Quad Stretch

Roll over the floor on your stomach and lie flat. Lie with a flat back. Keep your legs and neck in a relaxed position. Start raising your right foot and flex it at the knee. Lift your body slightly, reaching your back and using your right hand to grab your right foot. Use an exercise belt or strap to secure your foot in case you find it difficult to reach it. Pull up your leg upward and hold the stretch for about 20 seconds. You should then perform the same quad stretch with the use of your left leg.

What is Brachialis ?

Brachialis is a muscle located at the upper arm. Brachialis muscle flexes the joint of the elbow and assists biceps branchii in this endeavor. It forms part of cubital fossa’s floor. This muscle has its origin in the humerus’ front lower half close to the deltoid muscle’s insertion. Brachialis muscle embraces the deltoid muscle in two processes.

Note that the brachialis muscle does not participate in the forearms’ supination and pronation. This is because they do not insert in the radius.

Importance of Brachialis

The word ‘brachialis’ is a Latin word which implies ‘to the arm’. Irrespective of the grip that one is using during exercises, brachialis muscle has a key involvement in the elbow flexion. This therefore underlines the utility of the muscle in sports where pulling and grabbing are used. It also collaborates with the biceps brachii to create a crucial balance to the joint of the elbow especially for the people that use triceps brachii for overhead movements like hitting and throwing for example in handball and volleyball.
