«My body just can’t lose weight.» That’s the first thing I heard when I picked up the phone. Sounding frustrated and hopeless on the other end of the line, my client Sarah continued. «If you knew how hard I’ve been working, you’d understand. You’d know I wasn’t making excuses.»
Sarah first contacted me after a friend of hers had successfully lost weight through my online coaching program just six months after having a baby. I asked her to keep an open mind and walk me through everything she’d been doing in terms of diet and exercise. The problem was immediately clear: Sarah was putting in effort, but the type of effort-specifically her over-reliance on running for weight loss-wasn’t the best way to lose fat and get the results she wanted.
Once Sarah understood why her approach to cardio was holding her back, we adjusted her plan and the pounds starting coming off again (seven pounds in one month, to be exact.) So to make sure your cardio training isn’t the reason you’re not losing weight, here are five common mistakes, plus simple solutions to get back on track. (Here, more on running for weight loss, and other cardio myths that could be holding you back.)
Running for Weight Loss Mistake No. 1: Your Workout Is Always the Same
Your body is an amazing machine. It’s designed for efficiency, meaning if you do the same thing over and over again, the process becomes easier. This applies to your running workouts too. Not only will they start to feel more effortless (even if you’re still sweating and pumping your legs), but your metabolism learns and reacts so that fewer calories are burned with the same exercise output.

This is where traditional «steady state» running falls short on a long-term weight-loss plan. Research conducted at the University of Tampa found that doing steady state cardio-such as running on the treadmill for 45 minutes at a consistent pace that’s not near maximal effort (think sprinting)-helps with weight loss…but only initially. Subjects lost a few pounds during the first week and then kaput! Nothing more. The reason? Within one week, their metabolism had adjusted and now didn’t need to work as hard to burn off the fat.
One of the biggest problems with running at a steady, moderate-intensity pace, is that the calories you burn are limited to the time you spend sweating. So once your body adapts, the benefit is limited. That’s why weight training is oftentimes viewed as better than «just» running for weight loss. Lifting weights impacts your metabolism by causing mini-micro tears that need to be repaired. That healing process requires energy, which means you’re burning more calories-a process that can sometimes last for nearly two days after your training session.
To put it more simply: With cardio, you can slog away for 30 minutes at a lower intensity and burn 200 calories-or you can just eat 200 fewer calories per day. It’s the same thing. With weight training (or as you’ll soon find out-sprints), that’s not the case. The calories you burn are not limited to what you do in the gym. So while a little variety might not seem like a big change to your routine, it will have a dramatic impact on transforming your body.
Running for Weight Loss Mistake No. 2: You Go Longer, But Not Faster
One of the most important variables with any type of exercise-cardio or other-is intensity. If you look at the average person who runs, they pick a pace that they can maintain for a long duration. Think about it: When you jump on a treadmill, elliptical, or bike, you’re starting with the intent to be there for a while. Whether it’s 30 minutes or an hour, your goal is to push at a pace you can sustain, work hard, feel tired, and then go home. While this is great for endurance, it’s not so great for fat loss. (Because you know you’re wondering: Which is better, the elliptical or treadmill?)
A study in the Journal of the American Medical Association followed the exercise habits of more than 34,000 women and concluded that it took about an hour a day of moderate exercise (walking at 3mph) to maintain weight. Notice, that’s not weight loss. And three miles per hour is not very fast.
Now imagine if instead of arbitrarily picking an amount of time to exercise, you focused on pushing yourself to certain level of difficulty. If the 3.0 on a treadmill would be a «four» on a difficulty scale of one to 10, what would happen if you pushed yourself at an eight or nine for a shorter period of time?
There’s no need to guess, I’ll tell you: More fat loss. Researchers at the University of Western Ontario compared short but intense exercise to long, less-intense cardio. One group performed four to six 30-second «sprints» while the other group did cardio for 30 to 60 minutes. The results were nothing short of amazing. Despite exercising for a fraction of the time, those in the sprint category burned more than twice as much body fat. (This is all why HIIT training is so good for you-and for weight loss.)
That’s because the process of sprinting causes similar internal changes to your body as those that occur during weight training. Your body needs to replenish it’s ATP (energy), convert lactic acid that’s produced during exercise into glucose, and restore your blood hormone levels after an intense workout. All of those processes mean your body works harder and burns more fat-both of which don’t happen during steady-state aerobics. (That being said, you shouldn’t sprint every time you do a running workout for weight loss. Read this guide to interval running workouts for a full how-to.)
