An individual's workout schedule in weight training, also known as splits, for the different muscle groups depends on several factors. These include workout experience, training goals, availability and the time and rest needed to recover between workouts. Examples of training splits are the whole body split, upper and lower body split and the push/pull and legs split.
Those who are just starting out in weight training are usually advised to train more frequently, but with less repetitions and intensity compared to advanced lifters. Splits are designed ideally to meet an individual's specific goals, with the most common goals being to lose weight and to gain lean muscle mass. The number of days in the week where an individual has time to train, as well as the time his body requires to recover from the workout, should also be factored in when planning a training split.
As its name implies, a whole body split works out every muscle group in the body in a single weight training session. This split is for beginners and it involves just one exercise per muscle group with low reps and sets. Upper and lower body split refers to a workout plan wherein a workout session is dedicated either to upper or lower body muscle groups.
The push/pull and legs split refers to workout sessions that are divided into 3 days per week. This split involves a workout session dedicated to muscle groups for pulling, another for pushing and a separate workout session for leg muscles. More advanced lifters may take on 4-day to 5-day workout splits, with each split dedicated to working out just one muscle group.
