What does each letter in FITT stand for?

Frequency, Intensity, Time, Type

100

Which type of workout focuses on keeping your heart rate up for a long time, like running or biking?


Cardiovascular Endurance

100

During an arm curl, which main muscle is working?


Biceps

100

According to the Principle of Opposition, what would be the opposing muscle for arm curl?

Arm extension since arm curl is working bicep and arm extension is working tricep

100

Miss. K uses the nickname "dorrito back" for what major muscle?

Latissimus Dorsi

200

A person switches from running to swimming to improve their fitness. Which part of FITT did they change?

Type

200

Lifting heavy weights for fewer reps (like 4–6 per set) mainly builds what type of fitness?


Muscular Strength

200

During a chest press, what is the main muscle worked?

Pectoralis Major

200

What two muscle groups are opposites in your upper body during push and pull moves?

Pectorals and Latissimus Dorsi

200

What muscle helps you push forward in a push-up or bench press?

Pectoralis Major

300

What part of the FITT Principle is described:

"I lift weights 3 days a week"

Frequency

300

If you lift light weights for 15–20 reps per set, what type of fitness are you training?


Muscular Endurance

300

Which joint movement happens during an arm curl and an arm extension?

Elbow flexion (curl) and elbow extension (extension).

300

Explain how the Principle of Opposition shows up in a chest press and a row?


A chest press uses pushing muscles (chest, triceps), and a row uses pulling muscles (back, biceps) — they work opposite of each other.

300

1. What muscle corresponds with arm extension?

2. What muscle corresponds with arm curl?

1. Triceps

2. Biceps

400

A student’s workouts have stopped showing progress. Using the FITT principle, what’s ONE thing they could adjust to start improving again?


Change intensity (heavier weight)

Time (more sets/reps)

Type (different exercises) to challenge the muscles in new ways.

400

You lift moderate to heavy weights for 8–12 reps and start to see your muscles grow in size. What type of training is this?


Hypertrophy

400

Which muscles are mainly activated during an RDL (Romanian Deadlift), and what is their main action?


Hamstrings and Gluteus Maximus. 

Action: Hip Hinge

400

What does Principle of Opposition Mean?

While you work one muscle, its opposing muscle gets a chance to relax and recover before you switch to exercising it.

400

What muscle help you straighten your legs when standing up from a squat?

Quadriceps

500

If your goal is to increase muscular endurance, how would you adjust each part of the FITT principle compared to someone training for strength?


Frequency: Slightly higher (more days per week)

Intensity: Lower (lighter weight)

Time: Longer (more reps or sets)

Type: Resistance training focusing on endurance (e.g., circuit or bodyweight workouts)

500

Explain how a muscular endurance workout and a hypertrophy workout are different in both reps and weight used.

Include the intensity and reps


Muscular endurance: light weight, high reps (12–20)

Hypertrophy: moderate to heavy weight, moderate reps (8–12)

500

Match each exercise to its main muscle group:

  1. Overhead Press
  2. Squats
  3. High Pulldown
  4. Arm Extension
  1. Overhead Press – Deltoids

  2. Squats-Gluteus Maximus, Hamstrings, & Quadriceps

  3. High Pulldown – Latissimus dorsi
  4. Arm Extension– Triceps
500

How does the Principle of Opposition help when you walk or run?


Your arms and legs move in opposite directions to help you stay balanced and move forward.

500

1. What muscles keep your posture upright?

2. What muscles do you use to rotate your torso?

1. Erector Spinae & Abdominals

2. Obliques
