Jiu Jitsu is unlike any other martial arts on the planet. This is because you can train with 100% input everyday with little to no injury to yourself or your training partners. You will be sore each and everyday after training, but following some simple guidelines can save you and your training partner some unwanted doctor visits.
Have you ever been to a gym and seen someone who only has one speed and seems to injure everyone they train with? They use all of their strength in every movement, which only ends up causing injury to themselves and their training partners. This is typical behavior because newbies don’t have any technique or skill, so they really on strength to fend for their lives. If you are a newbie, try to learn how to defend positions and submissions; don’t be afraid to tap in training. The skill and technique will come to you with time. If you have more experience, help the new student with ways to defend a submission or a sweep.
Try to find a partner during the drilling portion of class that is close to your build. Finding a training partner close to your size will help you perform the technique much better. There is no reason a 200 lbs + person should have to drill with someone who is 120 lbs. There are weight classes for a reason, because size is an advantage. Don’t be afraid to roll with someone bigger than you though.
Invest in gear to protect you from injury. The number one purchase I highly recommend is a molded mouth guard. Buying a quality product will save you from spending a small fortune in a dentist office. Wear the mouth guard during warm-ups, drilling, and sparing; trust me accidents happen.
Keep yourself hydrated with plenty of water throughout the day; limit your intake of sugary caffeinated drinks. Staying hydrated will prevent muscle cramps, keep you from having heat exhaustion, and assist in preventing injury. I highly recommend purchasing a quality BCAA (branched-chain amino acids) powder to drink during and after training. BCAA has been proven to prolong mental and physical stamina and decrease in exercise-induced muscle breakdown and inflammation.
