| Goal | How the Program Addresses It | |------|------------------------------| | Build a solid strength foundation | Weeks 1‑3 focus on compound fundamentals (squat, deadlift, press) using the E170’s linear resistance curves. | | Improve movement quality & mobility | Weeks 4‑5 integrate dynamic mobility drills (hip CARs, thoracic rotations) that use the Smart Handles for proprioceptive feedback. | | Transition to high‑intensity conditioning | Weeks 6‑8 ramp up to HIIT circuits that blend resistance bursts (15‑30 s) with active recovery (jump rope, kettlebell swings). | | Develop “casting” confidence | The term “casting” references Selina’s analogy: casting a line—you start with a gentle pull (foundation) then reel in power as you master technique.
