Probably not. You might feel it after the first session but you should adapt pretty quickly. I'd suggest leaving out the tire flips as it is essentially a heavy hinge movement. You're loading your spine heavy three times a week - no need to do it a fourth time fÃ¼r the sake of conditioning. Also, you may find that if you pick only one of the exercises and attack it hard, you'll have nothing left for the other two. Just something to consider. Give it a try.
