I really like the more endurance-type workouts, so I'm leaning towards Meso 1. What concerns me most is the one-rep max calculations and the all the different weighted dumbbells. While I have a good variety of dumbbells, I don't have anything heavier than 15 lbs. Will I need heavier weights than that? Also, is it a must calculating the one-rep max? Can I get a good enough workout without it?
Also, I have 4DS and while I think it's a good workout, I don't like the supersets and all the changing of the dumbbells, so I don't do the workout. Is Meso 1 like that? I will say that HSC, BC and ME are some of my favorites and love the constant changing/pace of these workouts. But just not in 4DS. However, throughout those workouts (HSC/BC/ME) I'm pretty consistent using 8 lbs or 10 lbs throughout the entire program, at least for the upper body portions, so it makes it very easy going from one exercise to another.
