What Happens To Your Body When You Kickbox
While it may be tempting to practice your punches, kicks, and combos daily, even professional kickboxers keep their training to five or six days per week at most (via Men's Health). Kickboxing every day — or performing any high intensity interval training or extreme cardio every day with no recovery time — could potentially put you at risk for injury, so be sure not to overexert yourself. Most pros recommend practicing for about 30 to 90 minutes three to five times a week, depending on your commitment level and overall goals. When you are just starting out, you'll likely want to ease into training with three one-hour sessions per week.
Going to a few classes several times a week can provide some killer benefits with a low risk of injury — as long as you give yourself some well-deserved downtime in between sessions. According to a study on kickboxing injuries published in The Journal of Strength and Conditioning Research, the most common injuries associated with the sport are easily addressed strains of the shoulders, back, hips, knees, and ankles. Sprains and tendonitis were the second and third most common type of kickboxing injuries, respectively. The instances of these minor injuries, however, presumably decrease with proper recovery time and stretching prior to working out.
Overall, the study says there is a low risk of serious injury associated with kickboxing, making it a "safe form of exercise for fitness purposes."
