I'm on day 8 of the diet and I'm using the beginner training program. I'm using 100# DB on the DB squat and the weight is hitting the ground and limiting my range of motion (thighs not getting parallel). Would it be better for me two use (2) 50# DBs to improve my range of motion? I also went 9,8,8,8,7 on my sets so I think I need to go heavier. I just want to make sure I'm getting the most of the workouts while on the diet. Thank you in advance for the feedback.
