Which body parts should I target in a single workout?

Large muscle groups should be targeted separately throughout the week to allow adequate rest and recovery.

For example in a 4 day program you can target:

• Chest
• Legs
• Back
• Shoulders

All of these muscle groups can be performed on separate days while still giving the body time to rest. You can pair the smaller muscles with the larger muscle groups. These include:

• Triceps
• Biceps
• Calves
• Abdominals/Obliques 

Large muscle groups tend to perform better when they are paired with smaller ones.
