But every medal has themselves you know what. We have collected the five most popular fitness classes and their side effects.
Run
You do not know how to solve the problem - run away into the sunset. Or dawn, not fundamentally. Run is popular, useful and really helps to keep health. During jogging, all body muscles work, pumping cardiovascular system, and everything is filled with oxygen to one cell. Profit!
But if you do not keep the right posture during running, my legs do not spring with the grip with the ground, the body is overloaded. The risk of getting long and painful pain in the knees that can live with you decades. Many professional runners complain about sick knees, although the coatings are correct, and sneakers, and depreciation.
There is another one very big minus - according to the studies of Danish scientists, 45% of the runners are experiencing different problems of the gastrointestinal tract during running. The most common is incontinence of the intestines. And we do not joke!
Floating
Nice and helpful. Soft load on the whole body, stretching and muscle tone, taut skin and persistent immunity is a panacea from all diseases. Swim love all without exception, especially in comfortable, clean pools.
Do not forget that in most pools for disinfection use chlorine. The percentage of its content is of course regulate, but if you are allergic - the reaction will be immediate. And most often the fungus pick up just where wet and many people.
Bicycle
Pleasant, useful and fairly expensive sport. A good bike is like 5 pairs of brand shoes, but if you seriously want to ride, it is better to fork. Incorrectly selected, the convex seat can be brought to the compression of the inguinal arteries. But it is nothing, much worse when the nerve endings in the coccycle area and genital organs are constantly clarified - and this can already lead to serious illnesses. So watch the saddle!
Yoga
Cleans not only the body, but also the soul - so approve the adherents of the oldest practices. But do not forget that thousands of years ago, Yoga did not do everything in a row, but only the strongest. Therefore, if there is at least some problems of the spine, excess weight, hormonal background and even psyche, then yoga can be strongly pouched and not the best health. Where is fine - there and rushes. So where there are problems, there they will be aggravated. If you decide to start practices - get ready. Do not go into battle, especially since you are not able to fight with anyone.
Crossfit
No pain - no victories. Crossfit is a fashionable entertainment for desperate masochists. Yes, you sweat, like in hell, easily raise two own weights and run faster Panthers. But.
Crossfit is always a competition of strong, pumped and very beautiful athletes. Each of them behind the back or years in the simulator or army, or unreal genetics. Tear back in the first training session - easy. Grab microinsult, break the ligaments in two bills. But there is no pain - no victories, this slogan is written in blood in each crossfect room.
