Tether Ball Core Circuit [VIDEO]
A unique training circuit for a strong, athletic core.
This isn't cable ab training, it's not a kettlebell, there are no hanging leg lifts, no crunches, no machines and not even a TRX. Naudi Aguilar, owner of Functional Patterns, gives us a quick, four-movement circuit routine with a piece of equipment you've probably never utilized—a tether ball. Get you hands on one of these bad boys for your backyard, basement or makeshift gym and give this routine a shot.
