Start sitting down with both hands on crimps just above the lip. The left hand crimp is on the far side of the lip/roof. The starting right crimp is approximately 18 inches to the right of that, just above the lip. Make big moves alternating left and right, using the side-pulls, keeping compressed. Keep this alternating movement, while establishing your feet above the lip, and when you can, using a left hand side-pull with thumb catch and right hand high up on the right corner, set your feet, backstep on the starting crimp and throw up and over the center for a flat shelf.... or just continue tick tacking up.
