It’s important to know that rest is vital if you want to see the results. Because you use your legs, back, and core every day and they make up a large percentage of your body, you should only be doing legs twice a week. If you’re doing squats and deadlifts on the same day, you’ll want to rest a week in between workouts. They are both powerlifting exercises that challenge a lot f different muscles groups, doing both more than once or twice a week could increase your risk of injury.
