Core, core, core.
I include core in every workout — think everything between your hips and shoulders, both front and back.
The main core movements I always include are planks, side planks, situps, bicycle crunches, and supermans. You can create variety by using a gliding disc, stability or medicine ball, or other equipment.
A strong core keeps you stable in everything you do and allows you to do more work and move faster.
