Once you find a grip you feel comfortable with bring the bar up over your ears. Squat down and be prepared to spend a lot of your time here while initially learning. You may need assistance from someone pushing down on the small of you back to get you lower. Make sure if they do they have one hand on your back and one hand on the bar. As they release the stretch make sure they do so slowly. The first two years of your training should be directed towards gaining control in a deep squat with the weight over your head utilizing a snatch grip in conjunction with practicing the lifts daily. Focusing on this will improve your flexibility immensely and get your back straighter. Yes, while you are learning the OHS there will be some initial pain, this is normal and in time your body will adapt. The hips must go below the knees and your butt should be trained to reach the floor as closely as possible. Once this is achieved the next step is to make sure you can do it with your chest up and back straight. It is here younger weightlifters have an advantage over people who start a little later in life but, disadvantages can be overcome with stubbornness and hard work. I lived in the OHS holding onto a broomstick when I first started. I can remember being at work on my break and I would utilize the time to condition myself to this exercise. I am not sure what people thought of me but I didn’t care. I was excited to get better. I also did countless reps on the back squat which conditioned my hips to OHS lower while keeping my back straight.
