March in place, side step, grapevine.

If you are too tired to continue exercising in an aerobic class, march in place for a while until you can resume exercising.

If it feels too tricky or uncomfortable to bend or reach, just march in place.

motivul la care ma gandesc ca este mai mult un mars decat mers este faptul ca se face pe un ritm si de multe ori chiar daca este pe loc se ridica genunchi (deci sunt miscari mai exagerate decat un simplu mers pt a ajunge la un anumit ritm cardiac, etc.)
