For those of you who are looking for an effective way to decrease the soreness experienced from kettlebell training and speed up your recovery, check this Magnesium Oil out. Magnesium relaxes muscles and improves sleep quality due to the relaxation of the nervous system. It is best absorbed through the skin, and NOT the gut. Most of the oral magnesium supplements on the market are crap, and even if they were good, the mineral is poorly absorbed through the intestines in therapeutic dosages. An active adult should be supplementing with 300-500mg of magnesium a day, which equates to 24-40 sprays of this magnesium oil. Don't start there though, as magnesium also has a laxative effect that your body needs to get used to. Begin around 8-16 sprays a day.
