The best place I've worked out is at Knox fitness first, not because of the equipment, just purely because I was working out with a partner, a good mate, he was nothing special, hell, he hated working out, was more interested in the social aspect, but boy did we do some hard workouts.
saturday mornings where savage, I'd supervise his workout, in that I'd follow him round, setting up equipment and pushing him to his limit, then he'd return the favour, we hated each other.
at the end of the workout, I'd be lying on the floor, my forearms where so pumped up they'd be aching, I couldn't see properly.
