From the new CFJ article on the CFE War Camp:
Any of the hikers and mountain bikers we passed on the trail a few
hours before wouldn’t have believed or comprehended how a group that performed a challenging monostructural workout so gracefully was able to handle weight and perform a workout that involved kettlebell swings, pull-ups, ring dips and push-ups. This rounded capacity is really proof of the program’s efficacy.
Btw, the "challenging monostructural workout" was a 5-mile trail run.
