Your standard lunge does a nice job of making your derriere stronger, but to get glutes that function at their best, you need to start moving sideways, too. You see, when you do a side lunge or skaters, for example, you strengthen muscles in your outer hips. And strong outer hips can help you steer clear knee injuries. Plus, the sideways moves engage glute muscles so they can reap all the benefits of lower-body exercises. Not sure where to start? These exercises will help inspire you to work your glutes at a new angle.
Just because your hip flexor region feels sore doesn’t necessarily mean the muscles there are tight — in fact, they might need strengthening. This is where that sports science debate we mentioned earlier comes into play. It’s important to identify whether you’re tight or if the muscles are weak. Again, the Thomas Test will help you identify if you’re maybe stretching something that actually needs strengthening.
If you tend to stand with a "swayback," developing awareness of the opening at the front of your hips is especially important. In Tadasana (Mountain Pose), practice lifting the ASISes, moving the tailbone down, and lifting the lumbar spine. Putting a belt around your waist, as you did in Warrior I, may help you increase your awareness of your pelvic alignment in this pose too.
I HATE that the resistance training community can be so tribal. I have been preaching to bodybuilders for years about the benefits of powerlifting, or Olympic lifting or kettlebells or even Crossfit style conditioning and many have been receptive. Learn from each other and achieve levels of fitness you simply could not have otherwise. Don’t brush off bodybuilding wisdom…it could be the missing factor in your program.
