Muscles Working Together

• Chest: Works with triceps and front delts.
• Back: Works with rear delts, pulls from various angles.

Workout Splits and Routines

Push, Pull, Legs (PPL)

The PPL split organizes training based on movement patterns:

• Push Day: Chest, shoulders, triceps
• Pull Day: Back, rear delts, biceps
• Leg Day: Full lower body

Upper / Lower Split

4x per week alternating upper and lower days.

Full Body Split

Trains all muscles 3x per week. Great for beginners.
