Muscle Building 1 - Legs

A leg-focused workout primarily targets the glutes, hamstrings, quadriceps, abductors, adductors, and calf muscles. In terms of muscle building, it is recommended to begin the workout with compound movements which target multiple muscle groups at once, and then move on to isolated exercises. 

1. Barbell squats -   glutes, hamstrings, quadriceps, abductors, adductors, and calf muscles activation 
2. Dumbbell Bulgarian split squats - glutes, hamstrings, quadriceps, abductors, adductors, and calf muscles activation 
3. Machine leg extensions - quadriceps activation
4. Machine hamstring curls - hamstrings and calf muscles activation 
5. Bodyweight singular leg calf raises - calf muscles activation 
6. Machine abductor extensions - abductor muscles activation
7. Machine adductor closers - adductor muscles activation

For all exercises, choose a weight that pushes you but does not risk physical injury.
