How to do the Sandbag Floor Press, using the principles of StrongFit with Dr. Sara Solomon & Jackie Perez
Use a sandbag, or something that can be held between your hands (i.e. med ball).
Pressing is internal torque. Exhale through pursed lips on the concentric, and engage your external obliques, teres majors and pecs. Do not shrug (keep your shoulders down... so don't let them shrug up towards your ears). I like to think about pressing my hands into the sides of the sandbag to help me engage my pecs through the full range of motion.
