Meaning: 'Schedule' means to arrange or plan for something to happen at a specific time, in this case, setting aside time for workouts.

Wrong options:

• assign: Assign means to allocate a task or responsibility, which does not convey the idea of planning a time for workouts as effectively as 'schedule'.
• dedicate: Dedicate implies committing something for a specific purpose but lacks the direct implication of time management that 'schedule' provides.
• allot: Allot means to distribute or allocate, but it does not specifically indicate the act of planning a time, making it less suitable in this context.

Correct answer: high-intensity interval training (HIIT)

Explanation: The phrase 'high-intensity interval training (HIIT)' is the correct choice as it represents a specific type of workout that adds variety and intensity to a fitness routine, fitting well with the context of mixing different exercises.

Meaning: High-intensity interval training (HIIT) refers to a training technique that involves short bursts of intense exercise followed by rest or lower-intensity exercise, making it an effective way to challenge the body.

Wrong options:

• weightlifting: Weightlifting is a form of strength training but does not encompass the variety and intensity implied in the context of mixing workouts.
• aquatic exercises: Aquatic exercises refer to workouts performed in water, which may not provide the same level of intensity and variety as HIIT in this context.
• pilates: Pilates focuses on core strength and flexibility but does not convey the high-intensity aspect that is crucial for variety in a workout routine.

Correct answer: make sure to get

Explanation: The phrase 'make sure to get' is grammatically correct as it emphasizes the necessity of obtaining adequate rest and nutrition, aligning perfectly with the context of recovery being crucial for fitness.

Meaning: 'Make sure to get' means to ensure that one obtains or receives something necessary, in this case, adequate rest and nutrition for recovery.

Wrong options:

• avoid getting: Avoid getting implies a negative action, suggesting one should not obtain something, which contradicts the need for rest and nutrition.
• delay in getting: Delay in getting suggests postponement, which is not suitable in the context of ensuring timely recovery and nutrition.
• ignore getting: Ignore getting indicates neglect, which is contrary to the importance of obtaining adequate rest and nutrition.

Correct answer: improvements

Explanation: The word 'improvements' fits well as it refers to positive changes or progress over time, which is the focus of tracking fitness progress, making it contextually and grammatically appropriate.

Meaning: 'Improvements' means positive changes or advancements in one's fitness journey, indicating progress that can motivate continued effort.

Wrong options:

• setbacks: Setbacks refer to difficulties or regressions, which do not align with the positive sentiment of tracking progress.
• inconsistencies: Inconsistencies imply irregularities or lack of uniformity, which does not convey the positive aspect of progress that 'improvements' does.
• fluctuations: Fluctuations suggest variations or changes that may not necessarily be positive, making it less suitable in the context of motivation and progress.
