One of the things I like to do when I have smaller class numbers is to incorporate double kettlebell exercises. Having to control two separate kettlebells changes each exercise, requiring greater coordination and neuromuscular control. It is also an easy way to overload the core and hip musculature without creating modified exercises. Just by utilizing 2 bells instead of 1, you automatically get more activation of the core, and because of the need for more power, the hips work harder.
So here is your workout for the week:
Double Windmills: (1 bell in each hand) 3 x 5
Clean- Front Squat - Overhead Press: Blend all 3 into one movement. 5 x 5
Double Swing - 5 mins using Tabata Protocol (20 sec on, 10 sec off)
Perform this 2-3 times throughout the week.
