lol thats assuming your tempo would be identical from workout to workout.. its like saying hey hey I'm on a cut with a 200kcal calorific deficit by simply serving tucker from a smaller plate!

Answer: let it rip while popping out of the hole for some propulsion BUT losing abit of core/sphincteral stability = precious seconds wasted = Oops, yolo
