Home workout can be an excellent to health and well-being. It can be the only alternative or a complement, if the routine prevents going to the gym as regularly as desired or if the environmental conditions are not ideal for exercising outdoors. For those who like equipment, have some space available at home and prefer a low-impact aerobic workout , the exercise bike and the elliptical machine are among the most popular options. With regular training, both have benefits. Improve cardiovascular (aerobic) fitness (endurance). Their low-impact movements are ideal for those who need to protect the joints of the spine, hip, knee or ankle. There are also differences, and these can determine the choice. The exercise bike The exercise bike is probably the most popular physical exercise equipment. It does not require as many technical requirements, nor involves body weight support. It's an exercise done while seated, reducing the load on the joints and this is important for those who have balance problems or are overweight. It's simple to use and adjust, even for beginners. The price range for exercise bikes is wide, depending mainly on the type of resistance (electromagnetic, wind, or mechanical), the number of programs, and supporting software. The back support and wider seat of so-called recumbent models provide superior comfort, relevant for those who, for example, have spinal problems or are overweight. When choosing a bike, the important thing is to feel comfortable , and for that, the dimensions of the seat and handlebars need to be adequate or adjustable to the person's size. Only then, with the increase in exercise intensity, will the movement remain fluid and continuous. The disadvantage of the exercise bike, compared to the elliptical, is that it works a smaller percentage of muscle mass - that of the legs and, to a lesser extent, the abdominal muscles -, which can lead to fatigue before achieving the desired stimulus for the cardiorespiratory system. The mass participation in cycling or triathlon events and online group cycling classes have brought a new world of complexity in acquisition and price, but also of alternatives for those seeking to exercise by cycling at home. The correct position for using an exercise bike Position the seat to have: Knees slightly bent when the pedal is in the lowest position of the trajectory; Thighs parallel to the ground in the highest position of the trajectory. Keep your hands on the handlebars and lean your torso forward, without bending over. If the workout is prolonged, regularly change the position of your hands and torso to have get relieve. If you use clipless pedals, make sure their angle suits the geometry of your joints. The elliptical The popularity of ellipticals is due to the fact that they reproduce a movement similar to running , but without impact, and can combine the work of the legs with that of the arms. They are therefore an excellent alternative for those who have difficulty or do not like to practice running but want to maintain a similar movement. The workout is more complete and dynamic than cycling, as it involves more muscles: those of the trunk and those of the arms. The price range is wide, varying mainly with the type of resistance (electromagnetic, wind or mechanical), the number of programs and the support software. An important aspect in choosing an elliptical is the trajectory of the foot: the movement should be smooth, and the trajectory should form an ellipse. Most ellipticals allow to increase resistance and speed, varying the intensity of the exercise and the direction of movement (forward and backward) to eliminate monotony. The correct position to use the elliptical Keep your torso vertical (and not leaning forward) and place your hands on the side supports. Support the entire length of your feet on the pedals, with the tips of your toes pointing forward. Keep your hips aligned with your shoulders; In other words, avoid exaggerated lateral hip rotation movements. Keep your knees aligned with your toes, without being completely straight or bent when they reach the lower and upper positions of the trajectory, respectively. Other factors to consider For equivalent quality, ellipticals: Are generally more expensive than exercise bikes. They require a little more space at home. They are more difficult for beginners because they require more coordination. Ultimately, the choice depends on the goals and individual needs of each person. For a more complete workout, more space at home, and a larger budget, the elliptical is an excellent option. For something simpler, more comfortable, and possibly more economical, the exercise bike is ideal. The important thing is to maintain regular training and adjust it to achieve your goals.
