Yeah I thought thats a russian twist. The land mine is a recent invention, it replaced the lower corner of a wall in the gym. Although I have to say the barbell does some decent damage to the wall, even brick walls. Maybe thats why they made them.
Did you see these articles. I love how some people can look at things and get the completely opposite idea from them.

And then I find it funny that everyone recommends HIIT but...

Oh well, do what makes your happy... or low intensity physical activity.
Yah, I was hesitant to invest in an overpriced pivot, but even after putting a brick between my bar and the wall, the sheet rock in my garage was getting damaged, so I bought a landmine. I guess I'll call that exercise "Russian Twists" then, since that was the original, pre-landmine name. Whether one does them with a landmine or just bar against wall is irrelevant.
All those health/fitness/nutrition articles make my head hurt. Unless you're willing to educate yourself on physiology and read the respective methodologies of those studies carefully (which Alex Hutchinson shows, can be downright stupid: http://
www.runnersworld.com/health/too-much-running-myth-rises-again), it's hard to know who's telling the truth. All I know is that publications live by offering a never-ending series of contradictory facts that keep consumers coming back for more, searching for the truth. Same with all the exercise programs out there, and the endless articles in fitness mags or blogs, or joe-schmoe's exercise videos.
For me, it all comes back to going by feel. Last fall I ran half-marathonish distances before I was really in shape to do it. And I could tell my body didn't like it, and the last miles were often a slog. So in this case, running two hours or more was probably bad for me. And it took me a while to recover, although recovery time improved pretty well over the 3-4 months I was running this way. Still, I'm glad I did it, I'm glad to know I can do it, and I love the adventure and exploration of urban geography involved in a longer run . If I can build back up to those distances more slowly, and perhaps run them less frequently, which is my current intent, I have a hard time believing it's going to be bad for me. Just gotta use common sense and some somatic awareness about what lies within one's limits and current conditioning. I have no doubt that one can run marathons and ultramarathons comfortably, but so many people nowadays do them without being really fit for it, more as a test of their mettle and will, with a 'just finish' mentality. They probably do damage their bodies.
Like one of the commentators of the first article notes, you can do just about any form of exercise badly, or to excess. When I hear about lifters talking about all their injuries, I wonder what the hell they're doing. Don't they learn from their mistakes? It's like chronic running injuries. Speaking of lifting injuries, today my shoulder feels 100% fine, after a great deadlift/row/pulldown session yesterday. I got back up to 305, two one-rep sets, then 3x5x265. I was going to reduce to 225, but I could tell on my last set of 265 that my back was done for the day. It was fatigued, so I moved on to hip hinge swings, just 70 pounds, and did a bunch of reps of those. Just common sense, right? Pushing the deadlifts much more, even at reduced weight, probably would've increased my chance of injury.
Anyway, so I think stretching has helped the left shoulder a lot. The test will be tomorrow when I do my presses.
In general though, I think about one hour of moderate exercise per day is about right for most people. I just have a hard time believing that 30 minutes of walking every day is going to get it done, although walking and hiking are great, no doubt.
And I am going to try to do more sprinting, as suggested in one of those articles. Speedwork once a week, and then tempo pace another time, is probably the proper counterbalance to longer weekend aerobic runs for me. Kind of like starting off a lifting session with the heavy stuff, with longish rest intervals, then moving on to the lighter assistance exercises at higher reps and shorter rest intervals, to get the heart rate up and flush the muscles with blood. Just makes sense to vary intensity, duration, and frequency within and across workouts and fitness modalities.
