Hi Jane,
Thanks for writing and welcome to the alli fitness forum! Although you've faced many physical challenges, it sounds like you've achieved so much by losing nearly 30 pounds! You should be very proud of yourself and realize the strength and courage that you have!
By what you've told me about your workout schedule, it looks really well-rounded and very effective. By including a variety of workouts, including cardio on most days of the week, strength training, stretching, etc., you are maximizing your fat-burning/calorie-burning potential! It isn't unusual for weight-loss to slow down once you've lost a significant amount. This is because when you weight less, your body requires less energy (calories) to function, as well as you've reached a higher fitness level and you're body has adapted to it. When this occurs, it is time to change up your exercise routine and/or tweek your diet.
I would encourage you to continue to incorporate different types of exercises into your weekly routine. Try pilates/yoga and/or swimming! Add 2-3 minutes of higher intensity exercises while working out when it is physically doable for you. For example, increase the resistance while riding your recumbent bike and really challenge yourself for a few minutes, then return to the lower level.
For more advice with your diet, post a message to the on-line dietician. With the help of alli, a healthy diet and regular, structured exercise program, you should see positive results!
Best in fitness and health,
Kelli
