A lot of people, even ones who workout super consistently lack the ability to get full hip extension.
Why should you care?
Well without full hip extension you really limit your ability to activate your glutes. This causes a whole host of problems: back pain, poor posture, muscle weakness, saggy butt, tight hips, to name a few.
If you want to lose weight or gain muscle we need to be able to work hard, and do things that are pain free. If your glutes aren't strong enough or you lack the mobility to activate them it severely limits A LOT of your success.
In the video below I included 2 easy exercises almost anyone can do to include at the beginning of any workout you do, especially a lower body workout. While basic exercises fundamentally, these will have a HUGE impact across all of your training.
