My plan will consist of: 5-7 Days a Week Recumbent Biking 30-45minutes HR 130-150bpm increasing to 160-170bpm intervals for 3 Months Then alternating days with the above, in between days will be resistance bands to build muscle which I have purchased. 6 Months target to see what changes in symptoms, I'm on day 3 and already feel better even though I've got a cold!! I think the more we decondition ourselves the worse we get. I used to work in a shop for minimum wage with POTS on my feet 8 hours a day no issues, even eating big full breakfasts then getting back to work, I was lifting heavy things and pushing things around so good workouts, Then I got a desk job for 2 years, a car and a flat, I'd get up, go to work sit down all day, drive home, make dinner and then sit down and then sleep, repeat. SOO leaves me thinking why was it I was living a normal life even with POTS and it suddenly changed, the above is the only reason I can think of!
