If your heart isn't working well, using a treadmill can be tough. It might even cause a heart attack because it makes your heart work really hard.
If you're not used to exercising a lot and you push too hard during a workout, it can stress your heart and might cause a heart attack.
When you begin to get fit, don't rush. Take it slow, drink water, and pay attention to any signs your body gives you during exercise.
Before doing a hard workout, it's important to warm up your body. Not doing so can stress your heart.
If you're feeling really stressed, it's better to avoid the treadmill. Stress can make your heart work too hard.
If your family has a history of heart problems or if you're older, it might be safer to go for a walk instead of using the treadmill.
Not drinking enough water can make your blood thick, which could lead to a heart problem.
If you have chest pain, find it hard to breathe, or feel dizzy while on the treadmill, stop exercising right away.
If you use the treadmill in the wrong way, like having a bad posture, going too steep, or too fast, it can strain your heart.
It's not a good idea to use the treadmill alone. It's safer to have someone with you or get advice from a fitness expert.
