Listen up guys, injury sucks. But then again, so does having mediocre results in your training and performance. The answer? Developing the ability to train to your maximum intensity without harming yourself. This means a huge build up of lactic acid and a tearing of the muscle fibres, but in a controlled and safe way. If you're serious about performing the best vertical jump exercises, you need to be squatting hard as part of your routine. notice I said "hard" not "recklessly" Rule #1 - Use a spotting partner (or two). Getting the weight back up on the stands after the final rep usually comes into mind before the last rep, so make sure you're concentrating on training to the max and not worrying about getting stuck. If you don't use partners, the temptation will be to exercise slightly less intensely than you can in order to get the weight back up on the last push. Grab a couple of buddies for a few minutes and get them to be your backstop. Return the favour too, and they'll gladly oblige. The square frame known as the Power Rack can be a live buddy substitute, but the Smith machine can actually reduce the effectiveness of the exercise and isn't ideal. Rule #2 - Do not bounce at the end (squatted) part of the exercise. You can perform a deep squat, past the point of quads parallel to the ground safely and without damaging your knee ligaments as long as you don't bounce back up again. You need to keep the strain on your muscles, and away from your joints as much as possible. Plyometric and box jumps involve a different type of movement and are valid vertical jump exercises, but they aren't performed with a heavy bar so don't use explosive and ballistic movements when squatting. Rule #3 - Use a weightlifter's belt to support your lower back. Having a good skeletal alignment (ie. being upright) will support the bar and keep the stress in the correct areas. The squat exercise, when done correctly should place primary stress on your quadriceps, glutes but also on the erector spinae, which extend throughout the lumbar, thoracic and cervical regions in the groove to the side of the vertebral column. There is a bit of controversy about the effectiveness of weightlifting belts, but for the small cost of a belt and also the fact that they don't cause injury makes them a safety favourite. Rule #4 - Stretch your quadriceps and get the blood flowing to raise the muscle fibre temperature before beginning. This is a nice straightforward movement to include - simply squat without a weight for four sets of thirty seconds each. As in the weighted version, turn your toes slightly outwards and don't bounce your knees. Your objective is to free up and lengthen your hips, hamstrings and quadricpes. Rule #5 - Repetition is the mother of skill, but those reps need to be done right first time every time. A great way to do this safely is using the wall hug method. This requires no weight and allows you to build good form before the poundage on the bar increases. Stand facing a wall with your feet a little more than shoulder width apart, toes angled out and touching the wall. Place your palms against the wall, moving them up to ear level and then rest your chin on the wall, head up. Now squat down as low as you can without falling backwards. The reference points of chin and toes against the wall mean that you have to perform the exercise with a straight back and knees in line with the toes. Ask a buddy to critique your form, paying close attention to the straightness of your back and alignment of your knees. Squats are a supreme lower body exercise, and an absolute must as a vertical jump exercise. As I said at the start, it's a pity that more people don't perform them, as they will add power and driving force to your thighs. At the risk of repeating myself, train hard, train intelligently and train safely. Now go do it!!!
