Day 4: 30 second plank, 30 seconds slow mountain climbers, 30 seconds of “dead bugs” + today you’ll add a 30 second right side plank & a 30 second left side plank, repeat for 3 sets.

PS- This is a tough day but you can do it! Be sure to rest in between sets. And don’t forget to comment or share a video when you’ve completed today’s challenge. If you have missed any days or are just joining us now, all the videos can be found on our FB profiles or at youtube.com/therealniknik
