Today I have done 100 days of stretching in a row despite being sick with long covid. Minimum session is 5 mins to get the tick, but I usually do nearer 10, maximum seems to be 30 mins. There were definitely times that I'd happily have given up, bearing in mind that some days I am too sick to leave the house, but I just about managed to get it done. This seems to be just the right amount of exercise that I can cope with and it actually has some use for climbing, double win!
I can now put my whole palm flat on the floor from a front fold, can sometimes get my calves to touch the floor in a butterfly stretch and have added 30cms to my side splits. Well chuffed.
