The most important thing as a beginner is to get the technique down.

The back squat

A back squat is when you are under a barbell loaded with weights and you are squatting to depth – this means that the hip joint is parallel or below the knee joint – and you drive up from the squat.

The deadlift

Deadlifts work all major muscle groups. The goal is to drive the weighted barbell off the floor into a lockout position, and then to bring the weight back down to the floor safely, while remaining in contact with the bar.
