This one is for those of you with weight-loss goals, and I’m not pulling any punches. At the risk of sounding sexist, the vast majority of "cardio addiction" sufferers I have encountered have been women, but there are plenty of men in need of this advice:

Get off the treadmill and start lifting weights!

No matter what your goals may be, you will get the biggest bang for your buck by lifting heavy things in lots of different ways.

One big mistake that many people make when they are attempting to get fit or lose weight is underestimating the importance of strength and power.  You must lift heavy things, in many different ways, if you want to get fit by any respectable definition of fitness.  Yes, this applies to you regardless of your age, gender, or goals.

Ladies, this especially includes you!!!  I would love to be quoted as saying that lifting weights is more valuable for weight loss than cardio, aerobics, or any other such uselessness in which you attempt to “burn calories”. In many cases, your body-weight might be all the weight you need to begin with, but your goal should be some degree of progressive overload and increased strength.

Movements like squats, deadlifts, pull-ups, and overhead presses are the most effective, in my opinion.  These are all functional movements that translate beautifully into real life work.  Striving to be be competent at each of them is to strive to have more real life skill and capacity.

Beyond these basic lifts there are a heap of movements that would technically fall into the resistance training category; many more than I could ever mention here. Training tools like kettlebells, medicine balls, tyres, sleds, and ropes add many more options for resistance training. They are all amazing for strength, torching fat and increasing fitness.
