Sports Performance Coach Shares a 20-Minute Workout to Boost Longevity and Build a Stronger, More Functional Core
Let’s be honest: who doesn’t dream of having six-pack abs? A shredded midsection might help you look the part, but there’s a difference between building abs for show and training your core to actually perform like an athlete. Focusing solely on building the abs overlooks the obliques, deep stabilizers, diaphragm, and pelvic floor that truly drive movement. The core is a force transfer system responsible for how you absorb, redirect, and produce force through the trunk while your limbs do the work. Meaning, they're meant for far more than just flexing.
"If you train for aesthetics, you get good at isolated flexion," says Carmen Del Mastro, CSCS, sports performance coach for Unrivaled, the United States’ flagship 3-on-3 professional women’s basketball league featuring top WNBA players. "If you train for function, you build bracing, rotation control, and positional ownership under speed and load. That’s the difference between looking athletic and actually expressing force."
It might look good, but a six-pack isn’t a reliable indicator of strength or performance. Adding functional core exercises into your training, whether sprinkled into your workouts or saved for a focused finisher, builds athleticism in a way that translates outside of the gym. Not only will you feel more like an athlete, but functional core training also supports longevity, delivering physical benefits that help maintain independence as you age.
Below, Del Mastro shares a functional core workout designed to make you move better, feel stronger, and actually use that strength where it counts.

How to Do Stability Ball Plate Rotations
