This quick strength training circuit is designed to influence your brain and nervous system to engage your deep core and keep your pelvis tucked while doing upper body strength training. Use deep focus on form. I recommend taking a breath in as the DB lowers and doing an audible hiss breath as you draw in your deep core. I think of my pelvic floor lifting all more organs as my ribs reach and wrap around them to keep them safe. (This magic brain tricking works!) Press your feet into the ground and engage your glutes.
