Is it safe to keep exercising during pregnancy?

This isn't really a yes-or-no question - it depends heavily on what you were doing before and what your doctor says. Most pregnant people actually benefit from staying active, but the specifics matter a lot.

Generally, moderate exercise is considered safe and even beneficial during pregnancy. Walking, swimming, and stationary cycling are usually fine throughout. If you were already doing strength training or running before getting pregnant, you can often continue at reduced intensity, but you'll want to adjust as you go - your center of gravity changes, your joints loosen up, and what felt comfortable in month three might not work in month seven. The key is not starting something new and intense, and definitely listening to your body when things feel off.

What you absolutely need is clearance from your doctor or midwife, especially if you have any complications like gestational diabetes, preeclampsia, or placental issues. Even with a normal pregnancy, some people need to dial things back more than others. Avoid contact sports, anything with fall risk, and lying flat on your back for long periods in later pregnancy. Heat exhaustion is also a bigger concern when you're pregnant, so watch your intensity in hot weather. The general rule most practitioners use is that you should be able to hold a conversation while exercising - if you're breathless, ease up.
