Who Is It For?
People with a medium dumbbell and a mat who want a challenging, structured core session to build strength and stamina.
Who Is It Not For?
Not ideal if you have wrist or lower back pain, or are new to core training, as the planks and loaded crunches are demanding.
Key Benefits
Builds core strength and stamina with loaded crunches, side bridges and planks, topped by a short Tabata-style finisher.
Things to Keep in Mind
Keep your lower back supported in leg drops and flutter kicks, and drop to your knees in the planks if your wrists or shoulders tire.
