Day 8 is the second lighter day of the cycle, and it splits its two minutes between the lower back and the spine itself. The circuit runs alternating arm and leg raises, back arches, knee rolls and a knee hug. Nothing here is hard; all of it is useful, and skipping it is how a daily program starts to feel like a chore in week three.
Two panels build and two panels release. Alternating arm and leg raises are done on all fours, reaching one arm forward and the opposite leg back until both are level with your back - the classic test of whether your trunk can stay still while your limbs move, and a direct counterweight to the crunching work of the last week. Back arches then take your spine through its full rounding and hollowing range. The last two go face up: knee rolls, with the arms spread wide on the floor and the knees rolling from side to side, unwind the lower back and the obliques through rotation, and the knee hug closes with both knees drawn into the chest, letting everything the program has been tightening finally let go.
In the arm and leg raises, reach away rather than up - imagine lengthening between your fingertips and your heel, and keep your hips square to the floor. Take the back arches slowly enough to feel each part of your spine move separately. During knee rolls, keep both shoulders on the ground as the knees travel; the point is the twist, not the distance. In the knee hug, wrap your arms around the shins and rock gently rather than pulling hard.
Your spine spent three days flexing - today it gets to extend, rotate and unwind.
Make it Harder: This slot in the cycle does not take that request - stay in each position longer and breathe deeper into it instead.
Make it Easier: Keep the knee rolls small; a few inches to either side is plenty to free up the lower back.
