Meat Head Swing (Front Raise Swing)
To fix this, delay your arm movement by keeping your elbows on your ribs through the hip extension. Imagine that your arms are tied to your trunk. And again, practice the kettlebell deadlift: place the bell between the heels, hinge hips keeping arms on your trunk, grab the bell and stand up without letting your arms come off your trunk.
All the power from the swings should come from the hips, making the full extension of the hips and knees critical. The hips and knees should not be soft at the top of the swing. Think of it as a vertical plank.
To fix, stand up hard by driving feet into the ground. Make certain that at the standup position the knees are pulled up, abs are braced for a punch and butt is pinching a penny. To help train this, do a kettlebell deadlift, making sure that you are standing tall and all the above are engaged. Commit to standing tall and strong.
Video yourself and see if you are doing any of these things in your swings. Apply these corrections and you will see that you can become more efficient and powerful, and you may just find that you could apply some of these tips to other movements as well. Remember that movements are an inch wide and a mile deep! Swing away!
