Fundamental 1 was about building some baseline strength in the key areas, fundamental 2 is about learning the key movement patterns and starting to add some weight. 

1. Squat body weight 3×12-20
2. Deadlift lift weight 3×12-20
3. Reverse lunge body weight 3×12-20
4. Weighted single leg calf raises 3×8-12
5. Bulgarian split squat 3×12-20

Spend around 2-4 weeks working on this before moving to the next stage
