What better way to celebrate the holidays than with a killer ab workout! This 25 minute routine is the sequel to last year's Christmas Crunch.

This quick 15 minute routine is an ab workout with some tricep kickbacks thrown in! Kickbacks are great for the triceps but often times people go too heavy with their weight and end up not working the tricep effectively. I suggest using a 5 lb dumbbell (10 lbs for guys, 3-4 lbs for beginners) for the kneeling tricep kickbacks. Form is important so remember to squeeze the tricep in the straight arm position at the top of the movement.

This 14 minute ab workout is a circuit of 3 exercises repeated 3 times. The first move is done in a seated position. The second is a new plank jump variation. The third move works the obliques and inner thighs from a side plank position. The first exercise is very advanced so just do what you can and modify or rest when needed.

This core workout consists of a circuit of 3 moves repeated 3 times. Fire up the abs with this 15 minute routine!

I filmed this workout while it was snowing outside so I guess I could call this workout "Snowbliques!" Haha ;) This 24 minute circuit consists of 4 exercises, repeated 3 times. Each move focuses on the obliques (the sides of the abs).

What better way to celebrate the holidays than with a killer ab workout! This 15 minute routine focuses on the core with some bonus butt work thrown in!

This 10 minute routine is packed with lots of different exercises to help you sculpt your abs and strengthen your core. You will be on your way to a trimmer, tighter midsection with this workout!

In this 8 minute workout you will do 7 different variations of the superman exercise. These movements are great at strengthening the lower back. This routine may be difficult for most people so take breaks as needed.

This 16 minute routine gives you the option to sculpt your abs and strengthen your core with exercises all performed from a standing position. You will need one light dumbbell for this workout. I am using 5 lbs.

This 17 minute  ab workout is very controlled and deliberate. Breathing is very important when it comes to working the abdominals. Try to over exaggerate your breathing with this routine to really contract the diaphragm and squeeze the abdominal muscles. So you should be crunching at that exhale when the abs are at their tightest to get that deep contraction. These moves combined with cardio and a proper diet will help you see definition in your abs.

The 6 exercises in this 8 minute routine will push your abs to fatigue and have your abs begging for mercy!

You will need one dumbbell (I am using a 10 lb weight) for this 10 minute routine. 3 moves are repeated twice to really burn out the abs!
