Use a Canon 50mm f/1.8 lens. Set the camera to 1600 ISO, and set a custom white balance using Tv mode and a shutter speed of 1/60th. Then set the camera to M mode and the aperture to 1.8, and adjust the shutter speed, metering off the gym floor or some other mid tone subject until it shows a correct exposure. Hopefully, you'll get a shutter speed of 1/350th or faster. Set the camera focus mode to AI Servo, and for continuous shooting. Make sure you have plenty of card capacity. Use the centre focus point, and shoot small bursts of 3-4 shots. Forget about trying to use flash.
