Gymnastics-inspired moves are great for working your abs in a creative way that skips the sit-ups.

The instructor begins by demonstrating the form of the first three moves: pike up, straddle up, and crab hold. Not only will your abs be working overtime, but the range of these moves also challenge and build your flexibility.

After the first three sets, prepare for a series of planks, focusing on form and uniformity. End with a fun, dynamic exercise that shows just how challenging the alphabet can be. Click play below to see what we mean.
