Hi Guys,
I have recently started regularly training my body to increase my CO2 tolerance.
I found 30s to be the sweet spot at the moment. Not too easy and not too hard.
However, I feel a lot of stiffness on my shoulders once contraction kicks in. It's as if my shoulders are "contracting" as well.
In addition to this, I also start to feel some warm sensation inside my body.
Is this normal? Or is there anything I can do to avoid this? The shoulder stiffness adds to the discomfort.
I normally train while lying in bed (just before going to sleep). But when the shoulders start to stiffen, It feels like my body is constantly looking for a comfortable position, no matter how comfortable my initial position already was.
