Swissball Crunch with Dumbell
Posted November 9, 2009 – 8:59 am in: Pegasus Internet Training Program, Personal Training, Strength Training, Tennis Fitness The core includes the following muscles: Transverse Abdominis, Rectus Abdominis, Multifidus, External Obliques, Internal Obliques, Quadratus Lumborum and Erector Spinae. It provides a stable platform which launches all of our movement by stabilizing the spine. 
The core generates the rotational forces needed for many athletic movements including throwing, swinging, striking and twisting. It acts to resist or neutralize external forces such as gravity, contact or momentum. We are only as strong as our core. A weak core limits our strength capacity.
Start off using a light weight. Amer is doing this with a 25 pound dumbbell which is actually pretty light for him. A good goal is to do 2 to 3 sets of 20 reps a piece. That will certainly strengthen your core!
