There are three kinds of muscle recovery curves, the normal exercise amount is 1, the muscle level drops on the second day, and reaches a slightly higher level on the fourth day than on the first day. 2 light exercise, the muscle level on the second day is the same as that on the first day, 3 excess, and the water level on the fourth day is higher than that on the first day.
You obviously haven't regained your muscles. Your real strength is the weight you can bear within 6 times when you return to normal level.
