New farmer's walk handles for the gym.
In my gym, we run the Starting Strength novice linear progression for noobs. This, as commonly done, has a couple of problems.
The first issue is shoulders. From what I've observed lots of SS coaches and their clients end up with shoulder problems. A friend who's worked with cricket players said they found when they could do a bench pull of bodyweight, they were much less likely to injure their shoulders. In other words, pulling strength affects shoulder health.
Now, vanilla SS does have chinups, but like the powercleans these are often forgotten. So the first change has been to return to those basics, and actually do chinups - or barbell rows if the person is too overweight or old for this to be a realistic prospect.
The second issue is that everyone gets aches and pains doing novice linear progression; aches and pains are fine, it's when they become actual muscle strains, tendonitis and the like that I worry about it. Partly this is just the body going "WTF? you want me to actually do shit now?" but what I noticed was that the injuries are always in piddling little stabiliser muscles like the quadratus lumborum, never in the big moving muscles like quadriceps. So our working theory is that the big muscles adapt more quickly to training than the small ones; when you think of blood supply and so on, this makes sense.
A less aggressive progression in the first months has really reduced the number of minor issues popping up, but some still do. So I got the farmer's walk handles for the gym - if nothing else, doing these sorts of movements teaches awareness. You get scrawny young guys and say, "squeeze your lower back muscles" and nothing happens - a bodyweight farmer's walk should wake 'em up.
