start out slow but you aren't necessarily in any danger of your heart rate goes above a certain number...I do high intensity workouts and my heart rate goes up very high..I am in shape for it and both me and the baby are perfectly healthy. :) I would start out at 20 minute intervals and build up from there. If you do a more intense interval session-20 minutes is great but slower you may want to be on for longer to get in a good workout

Don't go over 30 minutes first starting out and on a low intensity. Less is fine but people make the mistake of overdoing it. Good job getting active again!

I could only handle 15 minutes anyways so 😂 @marce88

You're not suppose to let your heart rate get above a certain number. Use a very slow pace and maybe not for more than 15 mins
