This principle is also utilized among various athletes as well as those who are just working out to stay healthy and improve their physique.
What this means is that rather than working your entire body in one weight training session, you will separate your body into various sections and perform exercises for one section per workout. There are numerous ways to divide your body and all offer different benefits.
Common examples include dividing it into 2 parts include upper and lower body and push and pull exercises. The athlete can then perform each strength training workout 1-3 times per week depending on their time dedication to the gym and individual recovery abilities.
You can also use a 3, 4 or 5 way split. The possibilities are really endless. You may choose to work one body part a day, once per week. This is common among people training strictly for strength. They will hit the body part hard one day and then give it a full week to recover and grow stronger.
You may also have a particular weakness in one of your body parts and will decide to train that one more frequently than any of the others.
It’s a good idea to change your split periodically to ensure you keep challenging your body, keeping it guessing as to what comes next, as well as to keep you mentally fresh and motivated to work out.
Split routines are also beneficial for athletes as they help the athlete to put in shorter gym sessions at a time, which could prove to be helpful when they have other (sport specific) training to do as well.
