Guess we're on oppisite sides of the globe then, In my careerfield we focus more on endurance and cardio, your carrying about 50-60lbs of gear before you even add on a ruck so being able to move long periods of time with that much weight forces you to focus more on cardio and endurance training, thus I don't get much strength training, my lift weights are low, but I can go forever. The strength training we did on team was usually after 4-5 hours of previous running and rucking, the cadre just loved to torcher us like that, corse selection is more about breaking you down and seeing if you will quit then actual training. If your looking for a good endurance workout, try rucking, KBs are beast to. In the meantime I think i'm gonna steal some of your workouts, carrying around a 70lbs ruck when you weigh 143 ain't easy no matter how good your endurance is. Good luck with the training.
