That is a widely held belief, thankfully it's not true. Were it true, exercise would not be as effective in lowering blood glucose levels as it is.
Muscles will not take up glucose to convert to glycogen without insulin, but they will take up glucose from the blood for immediate conversion to energy. Insulin is not required for the take up of glucose for many tissues. Notably, nerves can utilize glucose without insulin.
