Are you a gym enthusiast? If yes, then chances are that you have spent most of your time on the cross trainer, or the elliptical machine. It is a cardio machine that for the first time gained traction in the 90s and is commonly used even today!

All thanks to its low-impact cardio exercise which can increase heart rate, burn calories and also aid in weight loss without much pain or injury related with running or jogging, that the cross trainer got its fame among people. Despite all this, one concern that looms over is safety, especially for those with weak knees.

Before we delve into how it affects weak knees, let's first figure out how a cross trainer works?

It engages the entire body on a vertical plane by combining the movements of running, stair climbing and skiing. The major difference is that the involved joints do not reach their full range of motion since the feet are planted firmly on the platform instead of being lifted from the ground. This also happens due to artificial movement that changes your natural gait and leads to knee pain because it is inconsistent with body's natural joint motion.

What Could Contribute To Knee Pain?

Improper Alignment: It forces your body to be in a fixed position against proper alignment. This is what leads to strain on your knees, especially if you are not properly positioned while using the elliptical machine.

What could be wrong with your posture? Your hips could be wider than the food pedals. Or, your knees may bow inward and place stress on the joint. Cross trainer also requires you to exercise on the balls of your feet, which engages the quadriceps muscles. This can also pull on the patella or kneecap and cause sharp or shooting pains across the knee.

Intensity: Lack of muscular strength is also a leading cause of knee pain and injury. This is because weak muscles do not absorb enough of the stress exerted on the joint and the knee pain thus continues. Identify if this is happening with you and see if it is because of the low intensity exercise from cross trainer that is not giving you enough challenge to build the necessary muscles to protect your knee.

Many experts have also pointed it that that low intensity machines could further overuse injuries in the knee and hip joints as those who are using do not realize that they are able to do more. This means it can make healthy knee joints weak.

Using Improper Force: Your body is strong and if you use improper force to do a certain exercise it can cause issues. Those with knee pain usually have a load tolerance equal to less than their body weight. So if you tolerance is equivalent to only 50% body weight, then it would mean that you are putting way too much pressure than required, which may keep your joint pain consistent.

Not Having Enough Rest: Whether or not cross training, after any exercise and before any exercise, it is important that you cool down and warm up! Taking rest days are also important as it helps you recover in case there is any muscle injury.

Our hearts works very hard to make sure we have the energy and strength to do everything we need. However, as gracious our organs are to us, most of us are not as helpful back to it. Whether it is eating junk food, not exercising, sleeping late etc. However, did you know, your heart is not the only one bearing the burden? You also have another heart in your body contributing to your health.

Heart transplant cardiologist Dr. Dmitry Yaranov calls your calf muscles your "second heart" for a very good reason. When you move your legs, these muscles squeeze and relax, which helps push blood back up toward your main heart.

This pumping action is essential for good circulation throughout your body. Without it, blood can pool in your lower legs, making it harder for your heart to work. By keeping your calf muscles strong, you help your body's entire circulatory system run smoothly, which can prevent problems like dangerous blood clots.

How Your ‘Sitting’ Lifestyle Is Killing Your Heart

Our modern lives often involve a lot of sitting, which is a big problem for our calves and our hearts. When we don't use our calf muscles, they weaken and lose their ability to pump blood effectively.

Dr. Yaranov warns that this forces your main heart to work much harder to circulate blood on its own. Over time, this extra strain can cause circulation to slow down, leading to swelling in your legs, high blood pressure, and a much higher risk of heart failure. No pill can replace the natural, powerful benefits of simply moving your body.

Simple Ways to Keep Your Calves Strong

The good news is that you can easily strengthen your calf muscles without a gym. Dr. Yaranov suggests simple changes to your daily routine. Try to walk every day to get your blood flowing.

You can also do calf raises while you're sitting at your desk or waiting in line at the grocery store. Whenever possible, choose to take the stairs instead of the elevator. These small, consistent actions will help keep your "second heart" strong and healthy for life, which in turn protects your main heart.

Calf Exercises You Can Do At Home

Calf Raises

Stand with your feet flat on the ground. Slowly lift your heels as high as you can, balancing on your toes, then lower yourself back down with control. Repeat for several repetitions to build strength.

Single Leg Calf Raise

Stand on one leg, using a chair or wall for balance. Lift your heel as high as possible, then lower it back down slowly. This variation helps improve your balance and builds strength one leg at a time.

Standing Calf Stretch

Stand a few feet from a wall and place your hands on it. Step one foot back and lean forward, keeping your back heel on the floor to feel a deep stretch in your calf. Hold for 30 seconds.

Dumbbell Calf Raise

Hold a dumbbell in each hand. Stand with your feet flat on the ground. Lift your heels and rise up onto your toes. Squeeze your calf muscles at the top before slowly lowering yourself back down.

Seated Calf Raise

Sit on a chair and place your feet flat on the floor. Place a heavy book or a dumbbell on your knees for weight. Lift your heels as high as you can, then slowly lower them for a controlled movement.

Weight loss injections have grown a lot in popularity as people flock to their healthcare professionals and nearby health stops to get one for themselves. Although it is rising in popularity, there are many side effects of the same. Many people find that different aspects of themselves have been altered after they took the weight loss injections along with some major bodily changes like loss of muscle mass.

Although these medications Ozempic, Wegovy, and Mounjaro—known as GLP-1 agonists—have become popular for their weight loss component, it was originally made for people with diabetes. Even though it is popular, the basic fundamentals of weight loss remain the same. A weight loss method that is devoid of exercise not only causes fat loss, but also muscle loss.

What Actually Happens When You Use GLP-1 Injection?

To understand how your body losses weight on weight loss injection, one must understand how this drug affects your body. GLP-1 agonists have three main effects on the body:

• They help the pancreas release insulin, which lowers blood sugar.
• They slow down digestion, meaning food stays in your stomach longer and releases sugar into your bloodstream more slowly.
• They affect the brain to make you feel fuller sooner and for longer.

You’re Losing Muscle, Not Fat

When you lose weight, you typically lose both fat and muscle. While some studies suggest that GLP-1s don't cause more muscle loss than other weight-loss methods, it's still a concern. A study published in the 2024 Diabetes, Obesity & Metabolism, suggested that muscle loss could be a big part of the total weight lost as much as 60% in some cases, while other studies show a much smaller amount.

Losing muscle can make you weaker, increase your risk of falls, and even reduce your bone density. This is why adding strength training to your routine is so important. It helps you build and keep muscle, which is key to a healthy and strong body.

Weight Loss Injections And Strength Training: Things To Keep In Mind

Talk to Your Doctor

Before starting any new exercise plan, always get advice from your doctor. They can give you a plan that is right for your health and the medicine you're taking.

Start Slowly

Begin with simple, gentle activities like walking. As you get stronger, you can gradually do more. Finding activities you enjoy, like dancing or cycling, will help you stick with it.

Mix It Up

A good routine includes a mix of different exercises. Try for at least 150 minutes of aerobic activity (like swimming) and two days of strength training (using weights or your own body weight) each week. Add in flexibility exercises like yoga to help with movement and prevent injury.

Monitor Your Blood Sugar

If you have diabetes, check your blood sugar before and after you work out. Your doctor can help you understand if you need to adjust your food or medication.

Stay Hydrated and Nourished

Make sure you're drinking enough water and eating healthy foods. This will fuel your body and help your muscles recover.

Listen to Your Body

Pay attention to how you feel during exercise. If you feel dizzy, unusually tired, or uncomfortable, it's a sign to slow down or stop. Your body will tell you what it needs.

For years, 10,000 steps a day has been seen as the gold standard for fitness. However, new medical perspectives suggest that walking fewer steps, if done correctly, can still provide significant health benefits. Hyderabad-based neurologist from Apollo Hospital, Dr. Sudhir Kumar, in a detailed post on X, explained why people should not feel discouraged if they fall short of the 10,000-step benchmark.

Rethinking the 10,000-Step Target

The 10,000-step goal originated decades ago as a marketing concept rather than a scientifically backed number. While it remains a popular target, experts now stress that the quality of walking matters as much as quantity. Walking at a brisk pace and steadily increasing one’s step count over time can greatly benefit cardiovascular health, especially for individuals with high blood pressure.

Dr. Kumar noted that the UK Biobank study, a large-scale health database, revealed how every additional 1,000 steps per day lowers the risk of heart-related conditions. Missing the 10,000 mark, therefore, does not negate the benefits of walking.

Evidence From the UK Biobank Study

According to the data, each 1,000-step increase in daily activity contributed to:

• A 17% reduction in major cardiovascular events
• A 22% lower risk of heart failure
• A 9% decrease in heart attacks
• A 24% reduction in strokes

These findings underscore that even modest increases in walking can create measurable differences in long-term health outcomes.

Brisk Walking Packs an Extra Punch

One of the most striking observations was that brisk walking during the most energetic 30 minutes of the day offered unique benefits, regardless of the total daily step count. Short bursts of faster-paced walking appeared to provide added protection against heart disease. This suggests that people who cannot reach higher step counts may still safeguard their health by incorporating short, brisk walks into their routines.

Lower Threshold, Higher Impact

Dr. Kumar emphasized that as few as 2,500 to 4,000 steps per day can significantly lower illness risk when compared with a sedentary lifestyle. This is especially encouraging for individuals who may struggle to achieve higher numbers due to age, chronic illness, or busy schedules.

He also pointed out that 1.3 billion adults worldwide live with hypertension, making walking an especially important and accessible form of preventive healthcare. Even small increases in activity, such as adding 1,000 steps daily, can meaningfully reduce complications associated with high blood pressure.

How to Start Building Healthy Habits

For those looking to improve their step counts, experts recommend a gradual approach. Increasing daily activity by 500 to 1,000 steps at a time helps individuals avoid burnout and makes it easier to sustain the habit long-term. Maintaining a brisk pace is equally important, as intensity plays a key role in cardiovascular benefits.

A Simple and Accessible Strategy

Walking requires no special equipment, gym memberships, or training, making it one of the most accessible strategies for improving heart health. Dr. Kumar concluded in his X post that people should focus less on obsessing over 10,000 steps and more on moving consistently, briskly, and progressively.

Ultimately, whether someone walks 3,000 or 9,000 steps, the key message is clear: every step counts toward better heart health.
