Back at it with another physical #smallandsimplechallenge . Do you want to strengthen your lower back and glutes? Do you need better posture? There are many benefits to this exercise so there’s no reason to wait. Do these for 30 seconds making sure to squeeze your glutes. See if you can get to 1 minute by the end of the week. If you need to make it easier, spread your feet wider and push your hips up with your hands on your butt. Want it more challenging? Try a resistance band around your knees. If you’re really into glute training follow @bretcontreras1 for tons of tips and techniques. The product giveaway will be announced tomorrow.Have fun!
