Core compression is the ability to fold your body at the hips with control. It's essential for L-sits, V-sits, handstand pikes, and any movement where your legs need to lift high. You'll start with seated pike stretches, progress to compression holds, leg raises, and finally L-sit and V-sit positions. This chain focuses on hip flexor strength and active flexibility. Train it daily—compression responds well to frequency. Most athletes see significant improvement in 2-3 months with consistent work.
