Hi
There are 2 main reasons for having panic attacks during exercise.
That for what ever reason, the body is under pressure physically, could be a virus, bio-chemical or problems from long term stress etc. So when the heart rate goes up too much the body goes into high alert!!
Then once you have had a panic attack in a particular place it is much more likely for it to happen again when in the same situation. The original presenting problem may have gone but the mind then forms a habit.
So if it is the latter, just find a time when you can relax and imagine going through the exercise and feeling calm and enjoying it, recall memories of how good it used to be , then get a glimpse of what it would be like when you can enjoy it in the same way again.
Happy keeping fit!!!!
