Side Straddle (Jumping Jack)
The SIDE STRADDLE turns each jump into a jumping-jack motion: your feet go OUT wide on one turn and back together IN on the next, alternating open-closed while the rope keeps passing. It adds lateral movement and inner/outer-thigh work to your jumping, and it's a building block for more complex footwork patterns.
