So I’m an ideal weight for my height but I feel really stiff and unfit, wobbly everywhere. Not helped by the fact I have fibromyalgia and ache almost all the time especially in my pelvis and my sciatica is agony. Been told I can’t do any HIIT. I did some yoga in the past was thinking yoga or Pilates or is there anything else. I’m also really tired all the time which doesn’t help. Oh and I hate swimming as the pool is always far too cold for me.
