We all have interests outside tech—my main one is competitive running—and every now and then I find an excuse to check out some piece of tech gear while working on my fitness. My latest effort along these lines is the Stealth Core Trainer, which promises to give me a “lean, strong core” while playing games on my iPhone.
You might ask why, if I’m a runner, I’m worried about core work. We runners have long been told that a strong core is essential for avoiding injuries and running well. I don’t disagree with this, though a decently strong core did nothing to prevent my most recent 18-month bout of plantar heel pain. I also found myself nodding when I read “Local Man Starting to Think His Core Will Never Be Strong Enough for Runner’s World” on the satire site Dumb Runner (be sure to check out the motivational posters too).
