Looking for a challenging routine for your abs?  Check out my newest video featuring a 4-exercise ab challenge.

What you need: 

An interval timer like the Gymboss

Do each exercise for 45 seconds, then record how many you were able to achieve/complete with good proper form, rest for 10-15 seconds, and move on to the next move.  Repeat this until you have completed all 4 moves.  

Move #1 – Lower Ab Reverse Crunch

Move #2 & #3 – V-sit Oblique Crunch (1st 45-seconds to the left, then to the right)

Move #4 – Mountain Climbers
