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.
Here is a recommended set range for each muscle group: 1  Legs - 14-20 sets. 2  Calves - 6-10 sets (possible twice per week) 3  Abs - 6-10 sets (possibly twice per week)  Back - 12-16 1  sets. Shoulders - 9-12 sets.  Triceps - 8-10 1  sets. Biceps - 6-9 2  sets. Forearms - 4- 3 8 sets. Traps - 3- 4 6 sets. Chest - 12- 16 sets.
