2. 2 What You Will Do Identify components or a resistance-training workout. Participate in a variety of exercises that build muscular strength and endurance. Describe the exercises that target major muscles. Identify various strength-training circuits and explain what each accomplishes.

3. 3 Terms to Know repetition (rep) set exercise circuit training large muscle group small muscle group

4. 4 Planning Your Resistance-Training Workout To be effective, a workout needs to follow a careful plan.

5. 5 Components of the Workout A repetition, or rep, is the most basic component of a resistance- training program. Repetition (rep) One completion of an activity or exercise. Term to Know

6. 6 Components of the Workout If you do ten push-ups, one right after the other, you have done one set of ten reps. Set A group of consecutive reps for any exercise. Term to Know

7. 7 Components of the Workout In a typical workout, you will do several sets of several different exercises. Exercise A series of repetitive muscle contractions that build strength and endurance. Term to Know

8. 8 Components of the Workout Every exercise has as its primary target a muscle group within one of the six weight- training “body areas.” ShouldersArmsBackChestAbdominalsLegs

9. 9 The Strength-Training Circuit Circuit training is the most efficient approach to resistance training for all areas of the body. Circuit training An approach to resistance training where you rotate from one exercise to the next in a particular sequence. Term to Know

10. 10 The Strength-Training Circuit One variation of circuit training is to work large muscle groups before small ones. Large muscle group Any group of muscles of large size or any large number of muscles being used at one time. Term to Know Working large muscle groups requires more strength, energy, and mental concentration.

11. 11 The Strength-Training Circuit Small muscle groups often play a supporting role in large muscle group exercises. Small muscle group Any group of muscles of small size as well as any small number of muscles being used at one time. Term to Know If small muscle groups become fatigued, large muscle exercises will be more difficult.

12. 12 Variations on the Circuit A second variation of circuit training is to alternate push exercises (extension) with pull exercises (flexing). This gives muscles time to recover and keeps opposing muscles balanced.

13. 13 Variations on the Circuit A third variation of circuit training is to alternate upper-body exercises with lower body exercises. This method allows muscles more recovery time, but it is more difficult than the other circuit- training options previously discussed.

14. 14 Variations on the Circuit A fourth variation of circuit training is to work weakest muscles first. By working weak muscles first, you can get the muscle back in shape more quickly.
