Which Workouts Should Be Avoided When You Are Overweight and How to Start Without Harming Your Joints

The desire to lose weight faster often pushes people toward the hardest workouts: running, jumping, intensive exercise routines, and exhausting cardio. The logic seems simple the harder the session, the more calories are burned and the faster the weight comes off. But for an untrained person who is significantly overweight, such a start may produce the opposite result. Instead of gradually strengthening the body, they may develop knee pain, back discomfort, excessive strain, fear of the next workout, and a long break caused by injury. Time for Action examined which workouts are better avoided at the beginning, why high intensity does not always mean greater benefit, and which forms of exercise help prepare the body for further progress.

Why You Should Not Start With the Hardest Exercises

The body adapts to physical activity gradually. The heart, muscles, ligaments, joints, and spine must become accustomed to a new mode of work. If a person has had a sedentary lifestyle for a long time, even ordinary brisk walking can become a full workout. Excess weight increases the load on the musculoskeletal system even in everyday life. The knees, ankles, hip joints, and back already work under additional pressure every day. During running, jumping, and sharp landings, this load increases.

Therefore, the problem is not that running or intensive workouts are bad in themselves. They can be beneficial for a trained person. But at the beginning, they often exceed the abilities of a body that does not yet have sufficient strength, endurance, or proper movement technique. The result of such haste is predictable: a person tries to follow a programme for which they are not yet ready, quickly becomes tired, loses control of their movements, and begins compensating for weakness with poor technique.

Running Creates a Load That Requires Preparation

During running, every step ends with the foot making contact with the ground. The body must absorb the impact, stabilize the joints, and immediately move into the next motion. The feet, lower legs, knees, thighs, pelvis, and core muscles all work at the same time. If a person is significantly overweight, has weak muscles, or has limited joint mobility, part of the work that should be performed by the muscles begins to fall on the joints and spine. Materials about running often give examples showing that impact force can be several times greater than body weight. This does not mean that hundreds of kilograms literally fall on the knees. It refers to the force that the body must absorb with every step. It is the repetition that makes the load especially noticeable. During a single run, a person takes thousands of steps. If their technique is unstable and the body is unprepared, even a small incorrect load is repeated many times. Therefore, running is not necessarily forbidden forever for people who are overweight. But it is better to move toward it after a period of walking, muscle strengthening, and cardiovascular adaptation.

Jumping and Burpees Can Be Even More Difficult Than Running

Skipping rope, jumping jacks, burpees, and interval routines with jumps are often promoted as quick ways to burn a large number of calories. They really do raise the heart rate sharply and engage many muscles. However, such exercises require good coordination, core control, joint mobility, and the ability to land softly. Without these skills, a person may land heavily, their knees may collapse inward, and their back may lose a stable position. The burpee is especially difficult. One exercise combines bending over, supporting the body on the hands, moving into a horizontal position, returning to a squat, and jumping. For a trained athlete, this is an intensive routine. For a beginner with a high body weight, it is several difficult movements in succession, each of which already requires proper technique on its own. If the main goal is weight loss, there is no need to push the body to exhaustion within a few minutes. Calories are not burned only during jumping. It is much more important to find an activity that a person can perform regularly without pain or prolonged recovery.

Why HIIT Is Not Always Suitable at the Beginning

High-intensity interval training is built around alternating periods of very active work and short breaks. It can be effective, but it places considerable strain on the heart, respiratory system, and muscles. An untrained person is often unable to maintain proper technique when their heart rate rises quickly. In this situation, they no longer control the movement and simply try to finish the set. Excess weight in itself does not mean that the heart is necessarily unhealthy. However, a sudden transition from a sedentary lifestyle to maximum exertion may cause severe shortness of breath, dizziness, a sharp rise in blood pressure, and overload. At the initial stage, it is therefore more useful to work at an intensity where the person feels the effort but does not lose control of their breathing or movements.

Walking Is Not a “Weak” Workout

Walking is often underestimated because it does not look as impressive as running or a difficult gym routine. In reality, brisk walking can be one of the best ways to begin for someone who previously moved very little. It does not create the same impact load as running, but it trains the cardiovascular system, improves endurance, and increases overall mobility. The main advantage of walking is that it can be easily adjusted. At first, it may consist of short walks at a comfortable pace. Then the duration, speed, or distance can gradually be increased. The recommendation to begin with 30–40 minutes does not suit everyone equally. For some people, this will be a comfortable amount of exercise, while for others it may be too long. The correct starting point is therefore determined not by a number, but by how the person feels. A person should finish the walk feeling that they have completed some work, but not with pain, severe exhaustion, or the need to recover for several days.

Nordic Walking Engages More Muscles

Walking with poles can be a good option for those who want to increase the load without moving on to running. With proper technique, the arms, shoulders, and back work more actively. This distributes the load across a larger number of muscles and makes the workout more intensive than an ordinary walk. At the same time, the poles alone do not guarantee a result. If a person simply carries them in their hands or places them incorrectly, the benefit decreases. It is therefore useful to learn the technique first instead of trying to walk as fast as possible immediately. The claim that Nordic walking always burns 20–40% more calories should be treated as an approximate estimate. Energy expenditure depends on pace, duration, body weight, and how actively the arms are used.

Water Reduces Pressure on the Joints

Swimming and water aerobics are especially useful for people who find prolonged walking painful or have difficulty performing exercises while standing. Water supports the body and reduces the load on the joints and spine. At the same time, water resistance forces the muscles to work. Movements become smooth, but not necessarily easy. Even ordinary walking in water can be a noticeable workout. Swimming also makes it possible to train endurance without the feet repeatedly striking a surface. However, calorie expenditure should not be assessed using one universal figure. The mentioned 400–500 calories per hour is only an approximate guideline. The actual result depends on swimming style, pace, technique, breaks, and body weight. Something else is more important: water allows people who quickly experience pain or fatigue on land to move for longer and more comfortably.

Exercise Bikes and Ellipticals Provide Controlled Cardio

Exercise bikes and elliptical trainers provide smooth, cyclical movements without jumping or sharp landings. A person can independently regulate resistance, speed, and workout duration. An exercise bike is often comfortable because of the seated position. However, it is important to adjust the seat height correctly to avoid creating unnecessary pressure on the knees. An elliptical trainer engages more muscles and resembles walking, but without the impact of contact with the ground. At the same time, it may be difficult for people with poor balance or low endurance, so it is better to begin calmly. The main advantage of these machines is the ability to increase the load gradually without making an abrupt transition to difficult exercises.

Strength Training Is No Less Important Than Cardio

Weight loss is often associated only with cardio, but strength exercises are also important. They strengthen the muscles that support the joints, help improve body control, and make everyday movements easier. Stronger leg muscles make walking, climbing stairs, and getting up from a chair easier. Developed back and core muscles help stabilize the spine. Strong arms and shoulders make household tasks easier. The claim that strength training dramatically “boosts metabolism” is often exaggerated. Muscle tissue does require energy, and preserving muscle is important during weight loss. However, the main benefit of strength exercises is not magical calorie burning at rest, but the fact that the body becomes stronger and more functional. Simple movements are suitable at the beginning: getting up from a chair, pulling resistance bands, and exercising with light weights. But even basic exercises need to be adapted to the person’s abilities. For example, deep squats may be uncomfortable if a person has limited mobility or knee pain. In that case, getting up from a chair is a more controlled option.

Proper Technique Is More Important Than the Number of Repetitions

At the beginning of training, the main goal is not to perform as many exercises as possible, but to learn how to move safely. If technique deteriorates after several repetitions, continuing the set does not add any benefit. A trainer can help adjust equipment, select the right range of motion, and explain the proper position of the knees, feet, and back. This is especially important if a person has never trained before or already experiences pain. But even working with a trainer should not turn into a test of willpower. A good beginner workout does not have to end with nausea, trembling legs, or complete exhaustion. A person may feel tired after a session, but they should not experience sharp joint pain, dizziness, or a significant deterioration in well-being.

Weight Loss Does Not Require Daily Punishment

One of the main mistakes is treating exercise as punishment for excess weight or food. This approach pushes a person to choose the hardest format immediately because an easier workout seems insufficient. In reality, results depend not on one heroic workout, but on consistency. Calm walking, swimming, or basic strength exercises performed systematically are more beneficial than one exhausting HIIT session followed by a break caused by pain. The best workout at the beginning is not the one that burns the most calories in one hour, but the one after which a person can safely return to training the next time. The purpose of the first few weeks is not to test the limits of endurance, but to build a foundation. Gradually strengthen the muscles, improve mobility, learn to control breathing, and become accustomed to regular physical activity. After that, the walking pace, resistance on exercise machines, weight used in strength exercises, and movement complexity can be increased. Over time, in the absence of pain and with sufficient preparation, short running intervals or more intensive routines can be added carefully.

People who are overweight do not need weak workouts, but properly selected exercise. Running, jumping, and difficult interval routines can wait. Walking, water-based exercise, smooth cardio machines, and strength training create a foundation on which further progress can be built more safely. Weight loss should not begin with pain. It should begin with movement that the body can manage today and gradually perform better tomorrow.
