Squat Rack or Power Rack?
The Squat Rack is a good choice for a smaller space, or when you need an easily disassembled, stackable and movable option.
A Power Rack is a more sturdy and a more all-around option than the Squat Rack, though it requires more space as a result. For example, the Power Rack already has space for weight plates, and no separate weight racks are needed.
Keep this in mind when squatting
Keep your upper body straight, chest forward. Be careful not to lean forward. Also keep your gaze forward so your neck stays straight and your back doesn’t get rounded. Squat low so that your knees are at a 90-degree angle and your thighs are parallel to the ground. Once you have the form down, you can deepen your squat even further.
Stand with your feet at the width of your hips with the tip of your feet slightly outwards. Make sure that your knees are parallel to your feet when squatting, in a way that your knees don't go beyond your toes. Keep your knees parallel to your feet during the squat and don't let them turn inwards or outwards. Keep the weight on your entire foot or heels during the squat.
