Step-by-step salary – Sabra

What is the explanation in the words of the Maga (which originate from the G.M.) that there is an interest in going to a distant synagogue because of the 'feet of walking'? What is the explanation for this? What is the honor in walking far when one can pray soon? And is there an explanation for walking on foot and not in a car (and the car itself is an old model and at low speed)? Or perhaps walking with tiny steps and limping? Or perhaps buying a heavy etrog because of the 'feet of muscles'? Also, why do we find this only with regard to a synagogue?
