2) Insist on aerobic exercise. Put away all your dumbbell treadmills. That's for fitness. What you need now is to lose weight.
Aerobic exercise can make you naturally fit in the embrace of nature.
3) Open mind. If you don't explain this, Chinese medicine will tell you why and what stagnation is.
To sum up, it is six words: shut up and take your legs.
I hope it helps you.
