You’ve no doubt seen it before: those giant exercise balls people perch on at the office, or the personal trainer sits on at the gym to “enhance core activation” or “burn more calories.”
Research studies show these things don’t actually engage the core muscles any more than a chair does, can actually increase compression on your low back, and definitely don’t burn more calories or improve posture.
My take: I completely agree, and I cringe every time I seen someone destroying their posture by slouching on a ball chair, while innocently thinking they’re somehow getting more fit. A better use for the ball would be ball push-ups, ball wall-squats, ball bridges.
Traditional static stretching (stretching and holding a muscle in a stretch for an extended period of time), especially when done prior to a workout, makes you weaker, and doesn’t reduce your risk of injury.
Research shows that after a bout of static stretching, strength can be lowered by 8 percent and lower body stability by 23 percent.
I normally use dynamic stretching and foam rolling to get ready for my workouts
CrossFit as the “kale of weightlifting,” which I’m sure will make most bacon and beef loving CrossFitters cringe lol.
Research that shows a high risk of injury among CrossFitters and the random, non-structured format of most of the training.
My Take: I’ve done CrossFit just to see what the hype was all about. I’ve competed against some very fit athletes who rely on CrossFit as their sole means of exercise. The problem with CrossFit is not, I think, the fact that the exercises are “bad” or that the training is non-structured. The problem with CrossFit is:
A) unfit people who join a CrossFit gym getting pressured into performing advanced exercises with poor form;
B) fit athletes getting pressured to compete against their peers even when they’ve already trained hard the day before; and
C) CrossFit coaches who can get lazy and simple start creating random workouts because they’re “hard.” But when applied intelligently and with good form, I actually think CrossFit workouts are a great way to get fit fast, just do it smart.
