Answer for question 1: option C: 8-10

FITT stands for:

• Frequency: How often you exercise
• Intensity: How hard your workout will be
• Type: What kind of exercises you will do
• Time: How long your workout will last

Strength training FITT guidelines:

• Frequency: Aim for two times per week, with atleast one day of rest between strength training sessions. (Strengthtraining can be done on cardiovascular aerobic exercise, or“cardio,” days.)
• Intensity: Start with lower weights, workingup to the heaviest weight you can lift for the entire set; aim formuscle exhaustion, which occurs when it is not possible to do evenone more repetition with good form because the muscle is tootired.
• Time: Perform each strength training exercisefor 8 to 15 repetitions, which equals one set. Do 1 to 2 sets foreach muscle group (biceps, triceps, chest, back, quads, hamstrings,etc.).
• Type: lifting free weights, weight machines,sit-ups, push-ups, pull-ups, leg squats, leg lunges, etc.

A well rounded fitness routine includes cardiovascular exercise,strength training exercises, and flexibility exercises.

• Cardiovascular activities include walking, swimming, wateraerobics, jogging/running, cycling, stair-climbing, using anelliptical trainer, and taking aerobic classes.
• Strength training exercises consist of using free weights,weight machines, or doing callisthenic exercises such as push-upsor sit-ups. These exercises build strength and endurance in themuscles and joints.
• Flexibility exercises such as yoga and stretching keep musclesand joints flexible and improve joint range of motion.

Strength Training

• Perform a minimum of six-10 separate exercises that train themajor muscle groups (chest, shoulders, back, arms, abdomen, hips,and legs).
• Do one-three sets of each exercise. A set is a group ofrepetitions without stopping.
• Do 10-12 repetitions. Repetitions are the number of times youperform a specific exercise without stopping.
• Work out two to three days per week.
• Perform exercises through a full range of motion.
