I come from a sports background, have always worked out in some way, strong and fit but not jacked and the gym is definitely not my identity. I've tried a variety of methods/programs and I think MTN Tough is the best option but I recommend modifying it to match your goals and lifestyle. Primarily because I always found myself slipping into areas of strength that are comforting (deadlift, bench press, pullups, military, jogging) rather than areas of weakness I need to improve on (single leg movements, hip strength, rucking, high intensity cardio).
There is a lot of intensity and I really don't like being super sore while enjoying my sports so I modify. For example, I'm in the Post Season Strength 2.0 program right now. But I'm also an avid skier and want to be mostly fresh going into the weekend so I can ski hard. Rather than following their 5 day program back to back I pick 3 and roll over to the remaining 2 to the following week:
Monday - Strength workout (D1)
Tuesday - Conditioning workout (D2)
Wednesday - Light run, walk, and yoga
Thursday - Strength workout (D3)
Friday - light run and walk
Saturday - ski hard
Sunday - light ski day or rest day
During the summer:
Monday - strength workout
Tuesday - mountain bike (fun cardio)
Wednesday - wade fish (rest day)
Thursday - strength workout
Friday - run and yoga
Saturday - hike and scout
Sunday - golf (preferably walking)
Fwiw, yes they provide daily prayer and mental toughness content but I don't feel like it's pushed on me at all. They also offer mobility, yoga, injury rehab/prehab, and nutrition content...but ya don't have to engage with it just like you don't have to engage with the other stuff.
