This is a tough one guys - that's why I showed you the Dead Bug & Toe Tap first. If you feel pain in your lower back, go back to those for a couple more weeks to build up more strength in your core, then come back to this one!
Perform this exercise for 8-12 reps for 3-5 sets. You can even put all 3 together as a circuit! Perform 10 reps of Dead Bug on each side, 10 Toe Taps, then 10 V-Ups all in a row for 2-4 sets.
