Thanks to one of our exercise physiology clients in Indooroopilly for a great question!
Hill climbing can be a challenge to the muscles of the lower body, whether you walk outdoors or on a treadmill. As a result, uphill walking can help improve the strength and endurance of the lower body muscles. But it will not completely replace the need for lower body resistance training.
You may feel that walking uphill is a physical challenge, and you are not wrong! The major muscle groups in your legs have to work harder to keep you moving, and that can certainly lead to greater strength development than walking only on a flat surface. Walking will only stimulate strength development up to a point though, and relying on walking for strength will mean you’ll also miss out on other important elements of fitness.
Resistance Training Develops and Maintains Joint Mobility
Most strength or resistance training exercises require larger movements than walking does. These larger movements are the key to maintaining joint mobility (the freedom to move your joints through a normal, full range of motion). This keeps you moving well and can reduce wear and tear on the joints – one of the biggest causes of joint pain.
Resistance Training Develops and Maintains Muscle Strength
Strength is important, even if you don’t see yourself entering any future strongman competitions. You need a minimum, basic level of strength to meet the demands of daily life, whether that means lugging a heavy bag or briefcase around all day, carrying the groceries, or picking up the kids. While any activity that makes you work hard will develop muscular strength to some degree, resistance training is the best for this. A dedicated strength-building workout will promote far more strength than any you might build as a by-product of other exercise.
Resistance Training Helps Maintain Movement Abiliity
The combination of strength and joint mobility will help you maintain your overall movement ability, agility, balance, and gait well into your golden years. These two components of fitness and musculoskeletal health are what give you the ability to catch yourself if you trip, reach overhead to grab things down from shelves, and generally maintain your ability to walk, jog, and run well throughout your entire life.
Resistance Training Helps to Maintain Muscle Mass
Around about your mid-30s, you’ll start to lose about 1% of your muscle mass every year. Over time, this has a huge impact on your movement ability (muscle mass is directly related to physical strength) – if you don’t take action. Your body will keep the muscle it uses. Use resistance training to maintain muscle mass and your muscle mass will keep you moving.
Over time, muscle loss can also substantially slow your metabolism, one part of why many people gain weight with age. Remember that old saying “muscle burns more calories than fat”? It’s true! Resistance training keeps your metabolism revved up, helping you more easily lose weight and keep it off.
So you can’t rely on the treadmill to build lower body strength. Do you have to join a gym? Not at all. If the rise of in-home personal training options and other at-home workouts tell us anything, it’s that you can get a great workout at home with little to no set-up. Our in-home personal training, exercise physiology, and coaching options do recommend a few different training tools, but you can start resistance training at home using just your bodyweight and branch out as you need to. You’ll probably find that you actually have a few things already lying around the house that you can use to provide resistance. Get creative and enjoy the benefits!
