I am a home gym typr of person. Right now i have a huge collection of hexagonal dumbells and a commercial grade heavy duty, adjustable incline/decline bench. My upper body is getting some nice muscle, but my lower body is suffering for obvious reasons (dumbell squats and lunges aren't cutting it! ). I need to add a really good squat rack to my collection of course with an olympic barbell and plates to go with it. Any particular squat racks you guys recommend, or would particularly avoid. I am considering a 'power rack' with a lower safety bar area, in case I am squatting alone and need to let the weight down on the lower bars.
