A four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees. Regular Polygon. A regular polygon is a polygon whose sides are all the same length, and whose angles are all the same. The sum of the angles of a polygon with n sides, where n is 3 or more, is 180  (n - 2) degrees.
Bigger muscle groups: 30-60 total reps per workout session. Smaller muscle groups: 20-30 total reps per workout session. Hence, your chest workout should have a total of 30-60 reps per workout because it belongs to the big muscle group. 3. Determine your ideal number of sets and reps: Because your goal is to build muscle mass, the ideal set/rep range for your chest workout is 3-4 sets of 6-8 reps or 2-3 sets of 9-12 reps.
If you want to get lean and ripped one of the best ways to do so is by increasing muscle density. In order to increase the density of the muscle is by using a lower number of reps with heavier loads.

The muscle will develop a hard, solid appearance if done over a period of time and if it is combined with low body weight percentage.
