Pliometrics is very popular now. It is often included into workout programs, it is mentioned in various articles and it is being widely discussed nowadays.
Despite the whole 'new and popular fitness current' fusion about it overseas, this type of physical activity was born in the USSR and was called 'impact method'. This method was developed by Yuri Verkhoshansky, the professor who used it for training track-and-field athletes at the beginning of 1980s. Then Americans invented a new name for it and spread the slightly changed methods of training into public. Throughout the whole process of popularization and adaptation the basic idea of the method got blurred and it earned a wider meaning. In the modern interpretation any exercises containing jumping are meant by pliometrics.

Why is pliometrics so popular today and is it worth adding its elements into your workout routine?

The original idea of pliometric exercises was developing the explosive power which is a capability of performing a large effort in a short period of time. The main exercise in the method was a spring down (jumping down from a box, instant impulse jumping from the earth surface in order to jump up on another box). This exercise is considered the most effective one for the power development, as well as one of the hardest exercises in the method.
But in the modern version there are plenty of other exercises in pliometrics which do not require such efforts and any specialized training.

What does pliometrics give to you?

1. It develops one's explosive power (muscular power). It especially applies to the lower body part.
2. It develops one's coordination.
3. It improves one's agility.
4. It helps to burn calories and speed up one's metabolism.
5. It improves one's neuromuscular proprioceptive sense (the body perception).
6. It stimulates quickly-contracting muscle fiber which is responsible for the power and which is susceptible to hypertrophy (growth).
7. It strengthens stabilizer muscles if those are not developed enough which lowers the risk of getting injured.

Pliometric exercises are usually performed by athletes aiming for certain tasks (runners, boxers, football and basketball players, etc.), as well as by those passionate about functional currents in fitness like crossfit. But they can and they should be used by all wishing to improve their physical condition, to speed up their metabolism, to burn some extra fat. If at least one goal of those stated above is on your list, you may start actively jumping on your workouts. Not only will it add intensity to your training, but some variety as well.

Safety issues

Like any other exercises, jumping requires strict rule obeying in order to avoid getting injured. As muscles and ligaments can get extremely loaded and cardiovascular system can get stretched to its limit, you should consider the following factors:

If you wish to start practicing regular pliometrics training in separate days when resting from weight training, you should be fresh and well-recovered. Avoid having jumping workouts more than twice a week.

This type of training is prohibited for those having issues with joints, spine, and cardiovascular system. Please consult your doctor before trying.

Wear comfortable shoes, preferably running shoes of high quality.

Make sure you warm up properly before a pliometric workout. You should get all warmed-up and stretched for the training.

Start with easier exercises and then complex them gradually.

Add supportive supplements to your nutrition plan, as such type of training gives huge loads on your joints and ligaments. And never forget about rich well-balanced nutrition and enough amount of water.
