עלייה במסת השריר וירידה בשומן. עלייה במסת השריר וירידה באחוזי בשומן לפי שיטתו של ד"ר יעקב עזרא. http://diet2all.net Lets dissolve the misnomer of "tone" right now. The firming-up or toning is due to an increase in muscle tissue as well as a low enough bodyfat percentage to see the definition and shape of the muscles and get rid of the "jiggle". Muscles do not go from soft to hard or hard to soft - they either shrink or grow in size. Muscles themselves do not "firm-up" or "tone". STRENGTH TRAINING & FAT LOSS FOR TONE There are no two ways about it - In order to achieve the look of muscle tone or a toned body you need to engage in strength training as well as shed the layer of fat covering your muscles. Traditional resistance training alone doesn't produce the toned look desired, especially when an individual resistance trains in the fashion previously mentioned with unnecessarily high repetitions, little resistance, and little if any stress on the muscle.
