we DO NOT gatekeep with this post! we’re poking fun at modern bodybuilding which emphasizes appearance and size far above performance and even health.
100% full respect to this guy! the only thing to laugh at is the social landscape which got us here :)
Carrying a heavy pack is really hard on the joints
Not as hard on the joints as heel striking on concrete in a run.
Depends on the weight of the pack and the terrain, it can be
A pack heavy enough for a fast walk to generate a sustained elevated heart rate, over a flat side walk, will create far less impact than a heel striking run on the same side walk.
For me, to elevate my heart rate as much as running, I’ve got to be carrying a 20kg pack up a loose rocky mountain pass, or practically jogging, either of which is quite rough. Just walking quickly on flat pavement isn’t nearly as effortful as running.
What is needed to generate the results varies from person to person depending on their fitness level, but the point is that, rucking reduces the rate of injury, particularly for people only have practical access to a hard surfaced environment for cardio.
