I have read articles that said the Squat and Deadlift are no different. What is the difference between the Deadlift and Squat? Can you accomplish the same thing as a Deadlift doing a Squat with a slightly different stance? The reason I ask is the Deadlift is too much on my back. But I can do the Squats with Dumbells to my sides. So in this program can I substitute the Deadlift with a different exercise with a leg machine or something?
