When it comes to treadmill training, people usually fall into one of two camps – they either love it, or they don’t. Maybe you find the treadmill a fun and convenient way to get your cardio in? Or perhaps you associate treadmill running with boredom, slogging through one mile at a time as you watch the seconds tick by?
Regardless of the category you fall into, there are some definite advantages and disadvantages to running on a treadmill. In short, it can be a fantastic tool to increase your sprinting speed and get an effective, fat burning workout.
If you’re debating whether to train on a treadmill or to run outdoors, there are a few points you might want to consider. Each comes with a unique set of benefits, so your goals will help you determine what makes the most sense for you.
Advantages of Running Outdoors
1. Increased Muscle Activation.
You might have noticed that running on a treadmill feels physically easier. When you run outdoors, you have to recruit more muscles overall, but especially your posterior chain which works to propel your body forward.
Running is essentially a plyometric movement that involves powerfully pushing off your back leg while driving your front knee forward to lift your body off the ground, landing and stabilizing on the front leg, then driving the back knee forward, and repeating. There’s a lot going on, and as a result you engage your glutes, hamstrings, calves, quads, hip flexors, and stabilizers (not to mention the actions of your core and upper body) just to run.
On a treadmill, you’re running against a moving belt that is basically pulling your legs behind you. Because you don’t have to push yourself forward, there’s a greater emphasis on your calves, quads, and hip flexors, and less activation of your glutes and hamstrings. As a result, there’s a lower energy requirement during treadmill running than running outdoors.1
The good news is, you can level the playing field here and increase your glute activation on a treadmill by setting the incline to at least a level 1.2
2. Variations In Terrain.
Running outside, which includes street running and trail running, often comes with variations in your running surface. I’m talking about inclines & declines (like hills), and even the slight unevenness of the ground. These variations cause your body to make biomechanical adjustments that expend more energy.
Also, there are usually obstacles during an outdoor run that force you to take bigger or smaller strides, jump over things, side-step, and pivot. These variations force you to move in different ways and make micro-adjustments, providing more variety and mental stimulation versus the literally straight-forward action of running on a treadmill.
3. Benefits of Nature.
The benefits of spending time outdoors and exercising in nature are endless. Being outside has been associated with decreased stress, increased happiness, and improved health. People who exercise outdoors have been found to workout longer, feel more tranquil after their workout, and workout more often than those who exercise indoors.3
Additionally, it’s the best way to get your daily dose of vitamin-D, an essential vitamin that plays an important role in your energy levels, immune system, and central nervous system.4
Running outdoors can also be more stimulating because there’s a constant change in scenery. You can get absorbed in your surroundings, lose track of time, and discover new places in your neighborhood. In a sense, running outdoors can be more about the experience itself, whereas running indoors tends to be more about the exercise.
Advantages of Treadmill Running
1. Weather-Controlled Environment
The reality is, you can’t control the weather. And sometimes, weather conditions can make it dangerous to exercise outside. Running indoors on a treadmill is something you can do at any time regardless of the weather, and sometimes it’s the safer option. Whether it’s incredibly hot outside, or there’s snow and black ice on the ground, you’re guaranteed a pretty safe run by taking it on a treadmill.
2. Easier To Push Yourself.
Running outside and really challenging your thresholds (especially if you’re training alone), can be hard. Especially when it comes to treadmill sprinting, training indoors can make it easier to push yourself.
On a treadmill, you’re in control of your speed, incline, and duration. With the push of a button, you can change any of these variables. That means, if you want to run faster, all you need to do is increase the speed of the belt. Unless you workout with some good wearable fitness tech or a running app, really pushing your limits can be more difficult when you’re going for an outdoor run.
3. Track Your Progress.
Because you’re in control of, and can see how fast and how long you’re running on a treadmill, it can be easier to track your improvements over time.
For example, lets say that you start out sprinting at a level 9 for 30 seconds. After a few weeks of consistent training, you might be able to increase your speed to a level 13 for that same amount of time. That’s some major improvement! And improvement is motivating.
Seeing the results and progress of your workouts can help you stay excited about training and stick to your workout plan. This is one of the biggest factors that makes treadmill training so great – you can immediately see your progress and ability to run faster, or longer.
Treadmill Workout to Boost Speed & Burn Fat
Now that you know all of the benefits of training on a treadmill, and how to get the same muscle activation as you would during an outdoor run, try this quick and effective treadmill sprint workout to burn fat.
Workout Instructions
- Set your treadmill to an incline of 1.5.
- Start jogging at a comfortable pace to warm-up your muscles.
- Perform at least 3 accelerations for 60 seconds each where you increase your running speed (to a fast run, but still below your sprinting pace) to prepare your body for max speed.
- Perform 5 rounds of 30-second sprints, taking 60 seconds of rest between rounds.
- During the sprint, you should feel yourself “going breathless.” During the rest, either walk or slowly jog to slow your breathing and heart rate.
Complete 5 Rounds:
| Sprint | 30 seconds |
| Rest | 60 seconds |
When you’re doing a sprint workout, the workout itself doesn’t have to be incredibly long. In fact, a longer workout isn’t always better, especially when you’re doing treadmill HIIT.
Your focus here is on pushing past your comfort limits. Because of the intense metabolic effect of this workout, it has a big impact on your central nervous system. That’s why, in combination with a fat loss nutrition plan, this fat loss running workout is definitely enough to stimulate weight loss.
Add this sprint workout to your routine either after your strength session or on alternate days for at least 4 weeks, and keep us posted on your progress!
