Drill Sergeant

We won’t ask why you like a strict authoritarian crackdown on your training, you absolute sadist… but you’d better turn up ready to work. This is military fitness with no holds barred – hardcore circuits with a tongue-lashing pushing you over the finish line. It’s open to all levels of fitness, but don’t expect to stand at ease.
