That there video is yours truly, submitting to a challenge on OpenAthletic a few months back (a pretty cool website--check them out at openathletic.com). The goal was 225# back squats, as many as possible, without stopping (no more than a second or two between each). I was sitting pretty at third place for all of a day and a half before some fellow came along and destroyed it with fifty reps!
I love squats--they're one of my favorite movements, for a couple of reasons. First of all, moving weight is just fun, and squats let you move a lot of it quite efficiently. Those 29 reps up there work out to 6525 total pounds moved (29 x 225) in a little under two minutes. Sheesh! I don't even like moving my furniture around at home, but there you go.
Squats are also great for more than just putting big pretty numbers on the board. They're a fantastic foundation movement--training your squat helps build your core stability and leg strength, which factors in to darn near everything you do both in the gym (olympic work, overhead, jumping, running...) and out of it (carrying groceries, lifting your kids, kung fu fighting, playing sports, climbing stairs, walking, having a great caboose...)
We'll be covering a whole ton of movements here in much more detail soon: how to scale them down to your level of fitness and how to expand your personal limits, how they all tie together, and most importantly, how they can impact your everyday life. We're bringing in actual experts (who don't say things like "great caboose") to break things down for us, as well as give insight into related topics like nutrition, injury recovery, and much more. It's going to be a good year.
Me? I'm your friendly neighborhood industrial designer. I'm hear to talk gear--how it's made, where to spend the money, ways to save it or DIY, stuff we like using, stuff we don't...and I'll even be sharing a few of my own designs. Watch this space.
