Exercise, HIIT, and Their Impact on Metabolic Health
Regular exercise plays a key role in improving metabolic health and reducing insulin resistance. The most effective approach combines aerobic exercises with resistance training. Aerobic exercises include brisk walking, swimming, and cycling, while resistance exercises such as balanced weightlifting and squats are highly effective for building and maintaining muscle mass.
Key Guidelines for Exercise:
Exercise Intensity: Activities should be performed in a way that does not cause breathlessness, in order to prevent elevated cortisol levels, which can increase blood glucose. Therefore, interval-based exercise, such as HIIT (High-Intensity Interval Training) and SIT (Sprint Interval Training), is recommended.
Timing of Exercise: Exercising in the evening or at night may have greater benefits.
Exercise Duration: It is recommended to engage in 150–300 minutes of exercise per week, or 30 minutes daily. If time is limited, even 10 minutes of walking after each meal can be beneficial.
Moderate Intensity: Moderate-intensity exercise, which raises heart rate to approximately 50–70% of maximum heart rate (around 120 beats per minute), is suitable for improving metabolic function.
By following these guidelines and combining aerobic and resistance exercises with proper nutrition, insulin resistance can be reduced and its associated symptoms and complications can be significantly improved. Just 30 minutes of daily exercise is sufficient to effectively enhance metabolic health.
Aerobic Exercises
These activities increase heart rate and improve cardiovascular function, including:
Brisk walking
Light jogging or interval walking/running (recommended in HIIT or SIT format)
Cycling
Swimming
Resistance (Strength) Exercises
These exercises help strengthen muscles and improve metabolism:
Balanced weightlifting
Squats and basic strength exercises
Key Guidelines (Reiterated):
Exercise Intensity: Activities should be performed so that they do not cause breathlessness, and interval training such as HIIT and SIT is very effective.
Timing of Exercise: Exercising in the evening or at night has greater benefits.
Exercise Duration: Recommended 150–300 minutes per week, or 30 minutes daily. If time is limited, 10 minutes of walking after each meal is also beneficial.
Moderate Intensity: Moderate-intensity exercise, raising heart rate to 50–70% of maximum heart rate (around 120 bpm), is recommended for improving metabolism.
Minimalist Workout “No Equipment”
This workout is designed to be performed at home or in small spaces using bodyweight and simple equipment like a backpack. The goal is to improve muscle strength, core stability, and flexibility.
Main Exercises:
Split Squat
Sets: 2-3
Reps: To failure (10-20)
Notes: Perform all repetitions on one leg at a time. Step far enough to be comfortable at the bottom position. Most of the work should come from the front leg.
Push-up
Sets: 2-3
Reps: To failure
Notes: Keep shoulders down and elbows tucked in. Lower and push up with full control.
Elevated Glute Bridge
Sets: 2-3
Reps: To failure (10-20)
Notes: Lie on your back with feet elevated. Brace your core and lift your hips by pushing through the heels.
Backpack Row
Sets: 2-3
Reps: To failure (10-20)
Notes: Fill a backpack with books or weights and perform a bent-over row with one or both arms.
Jackknife / V-up
Sets: 2-3
Reps: To failure
Notes: Lie on your back, brace the core, keep the lower back pressed into the floor, and reach hands toward your feet. To make it easier, do not lower the legs as far during repetitions.
Bodyweight Alternative Program:
Bodyweight Squat
Sets: 2-3
Reps: To failure
Notes: Keep the back straight, feet shoulder-width apart, and engage core and glutes.
Push-up
Sets: 2-3
Reps: To failure
Notes: Keep the back straight, feet shoulder-width apart, and engage core and glutes.
Alternating Leg Kickout
Sets: 2-3
Reps: To failure
Notes: Lie on your back, knees above hips, press lower back into the floor, and kick legs back and forth in a controlled manner.
Beginner-Friendly Minimal Equipment Program:
Sit to Stand (from a low chair)
Sets: 2-3
Reps: 10-20
Notes: Feet shoulder-width apart. Lower down to sit and stand back up without letting the knees collapse inward.
Incline Push-up
Sets: 2-3
Reps: 10-20
Notes: Keep shoulders down, elbows tucked in. Focus on the chest, not shoulders. Lower with control.
Alternating Leg Kickout
Same as above
General Guidelines:
Frequency: 2 times per week with at least 1 day of rest between sessions
Intensity: Perform each set to failure (maximum repetitions) or until proper form breaks down
Exercise Order: Complete all sets of one exercise before moving to the next
Rest: 1–2 minutes between sets or until muscles feel recovered
Progression: Increase difficulty or rep range once the target rep range is exceeded for any set
