According to Kim Preveza, a yoga instructor, the best full-body workout at home is a plank. She adds, “It works the whole body. It can be done on the knees if a full plank is a too much effort. It can also be done on the elbows if it is too much strain on the wrists or elbows. Also, it can be done on the wall or the kitchen counter if a plank on the floor is not accessible.”
