True

* People are still using machines at the gym. Get off the machines. They are about the most ineffective use of your time in the gym as eating a McDonald’s Quarter Pounder in the men’s locker room. The only time I would recommend using a machine is for direct joint or muscular rehabilitation. If you don’t fall into that category, use free weights. They force your brain to learn how to control an external object (the weight) and not just operate on a path set by a machine.

* Separating cardio and weight training. This goes along with the high-intensity tip. Save time, increase your intensity: Combine cardio and weights into one workout. Take the time you would normally spend on the treadmill (or any type of cardio) and divide it in half. Then spread it out into sprint intervals throughout your weight training. Voila! A beautifully effective workout.
