@bldssphq So i was just watching a video where a guy explained (I'm looking into the science, as he posted sources) that you only need 10 muscle specific exercise sets to get the full 100% strength and muscle benefits for each muscle a week. He then explained that doing 1-5 sets returns 64% and 6-9 sets returns 84%. So doing 3 sets of, for example, bicep curls once a week would still give you ~64% of the benefits, and adding another 3 sets a second day would put at about ~84% of the benefits. So just doing the strength portion already does you pretty good, and the other portions throughout the week likely get you close to 100%, if not there. With the time constraints available to most people (as mentioned by others), that's pretty damn impressive, since outside of the strength portion each day there's normally also an endurance and/or cardio portion.
And I don't know about other boxes, but at mine, for people who do have that 90 minutes+, the coaches are more than willing to tweak and adjust to help those people who likely have goals outside of fitness and strength (body building competitions and official CrossFit competitions, etc.). But for the rest of us on time limits, the 60 minutes is not only good, but damn pretty damn great for what we want. Not judging, because if you want and can do those 90 minutes (I wish), then more power to you. But at this point in my life, unfortunately, I can't, but I still get huge returns from what we do (and will get even more once I start eating a little better).
Forgive me my lack of proper terminology, I'm still new and learning!
