Learning how to front squat is probably a very sensible move if you want to increase your vertical jump. You see the front squat is one of the very best strength exercises for athletes wanting to learn how to jump higher. It has a number of benefits over the traditional back squat (better quad involvement, easier on the lower back being the main ones) and in theory isn't that hard to perform.
Basically you un-rack the barbell with it positioned across your shoulders, then while maintaining an upright position, you squat down until your thighs are just past parallel, before extending the knees and hips back into the beginning position.
Unfortunately many athletes miss out on the benefits this great exercise provides because even though it all sounds quite simple, in practice it can often be uncomfortable to perform if you are unfamiliar with the lift.
The reasons for this are that compared to the back squat, the front squat shoulders the load (pun intended) across a much smaller surface area. This means that on each of the parts of the shoulder where the bar is resting, it is carrying a higher portion of the weight. As well as that, many athletes, myself included, have wrist and back flexibility constraints, that can make this exercise difficult to perform when compared to the back squat variants.
However, just as there is more than one way to skin a cat (Apparently. I have never actually tried skinning a cat), there is also more than one way to front squat. In the video below I demonstrate for different ways to execute front squat, each with its own set of pros and cons, but all highly effective.
If you are interested in buying the front squat harness, and it truly is a great piece of training equipment, then you can order them directly from Getstrength.com and they do at least offer free shipping worldwide.
If you aren't using the front squat in your vertical jump program because you don't like doing them, then maybe it is time to give the front squat another look. They are a great vertical jump exercise and as I have just shown there are plenty of options available to you if are prepared to experiment a little.
NOTE: It is also worth noting too that I have focused on ways to shorten the learning curve of front squats in this article. If you are planning on doing some Olympic lifting as part of your program, which does require you to learn the front squat position in order to finish the various cleans etc, there is no reason why you can't take the time to work on the things that are holding you back. It might take a bit longer but it will be time well spent.
