Part 1 in my mind is PTTP, a strength-focused text. Part 2 is the original Russian Kettlebell Challenge book, which introduced us to many things about the kettlebell, including strength-endurance.
This combination, low-rep training for limit strength _plus_ higher rep training for strength-endurance, has been our formula for health/fitness/GPP since day one, at least in my mind - I've been doing kettlebell swings since 2001. No one says it's the end-all, be-all for every human being - athletes need to adjust their training for maximum effect on their individual, sport-specific performance - but it's certainly a great place to start and, for many, all we'll ever need.
@Kozushi, you sound to me like you're thinking about these things very well for yourself, finding the right combination of movements and training plans to keep you healthy, feeling good, and improving on the mat.
