"Use your Abs!!"

How many times have you heard a trainer mutter this phrase to a sweat drenched client. Sometimes trainers will coach their clients to "Use your abs" with every single exercise. Push ups, "Use your abs!!". Squats, "Use your abs!!". Single leg donkey calf raises, "Use your abs!!". I can see the client thinking, "What exactly does he mean?. How is using my abs going to get me to to move this weight?". It's not!! Your moving body parts are going to move the weight for you. How are you supposed yo use your abs during a push up? How are your abs going to get your chest off the floor? I do not know.
A more appropriate term to use might be "Brace". Tighten up your abdominal section like George Forearm was about to punch you in the midsection. Bracing is not going to help you move the weight, but it is going to help you stabilize your core. When performing any type of compound movement, you know how important core stabilization is. It's going to protect you from injury and help you move optimally. "Brace", don't "Use".
