They key to having great looking legs is based on targeting the primary leg muscle groups and shaping them to your desired size. Having strong legs does not necessarily meet the aesthetic appeal of both men and women, so the exercises must be tailored slightly reflect your personal desired outcome.
The shape of the legs is most defined by the shape of the calves, hamstrings and the quadriceps. These are general terms for groupings of leg muscles, but they comprise the large shapeable upper and lower parts of the leg. For men, large defined quadriceps and calves are often what constitutes attractive legs, but women’s taste differs in sizing and definition. Some women dislike the look of overly defined muscles and therefore will need to follow a regiment that focuses more on repetitions and endurance rather than strength.
Quadriceps and hamstring regions are most easily defined through leg presses and squats. Increasing weight with fewer repetitions will enlarge these muscles but maintained weight at increased repetitions will tone. Calves can be defined practicing weighted calf lifts or any exercise that utilizes balance on the balls of the feet. Those wishing to tone rather than enlarge should consider aerobic leg exercises.
