During DYN training, in my last 30 meters, my legs feel sore and tired and my hands feel numb.
Is this a signal of lacking O2 or the accumulation of CO2? I am not sure so that's why everytime I run into such situation I am worried that I might be out of O2 so I stop swimming.
And what does you usually do when you run into such feeling? You try you best to ensure the sore and tiredness in your legs and keep your current speed or you slow down your legs kicking a bit to make it more comfortable?
Thanks.
