Zone 2 Training

Lose weight without vigorous exercise

 

Sounds too good to be true. But there is a way and it’s not by vigorous exercise. In fact, quite the opposite.  It’s by reprogramming your mitochondria to utilise fat for energy. To achieve this we need to adopt zone 2 training 3 times per week.

Zone 2 training is exercise at an intensity that utilises the highest amount of fat oxidisation for energy (aerobic metabolism). It does this by stimulating all the slow-twitch muscle fibres to their fullest. If the exercise increases in intensity the body will start using fast-twitch muscle fibres and switch to glucose for fuel (Anaerobic metabolism). We want to stick to the fat-burning aerobic metabolism.

Zone 2 training is at a low intensity.

This low intensity will vary from person to person, athlete to athlete. But a good guide would be an intensity where one could carry on a conversation whilst exercise. Not getting out of breath.

This low-intensity workout increases our mitochondria and makes them more efficient in utilising fat for energy.

A well-trained athlete typically has 3-4 times the size and amount of mitochondria in the muscle compared to a normal person.

Zone 2 training is not training for fitness or muscle growth, though these are a by product. The primary goal is to re-programme the mitochondria to be more efficient in fat oxidisation for energy rather than switching to glucose.

People with type 2 diabetes have a poor ability to oxidise fuels. They use more glucose than fat at low intensity or even resting. These points to mitochondria dysfunction. In these cases, the mitochondria is just not efficient in using fat for fuel but instead opting for glucose. This is why many people struggle to lose weight no matter how hard they train. Hard training increases blood sugar levels but doesn’t burn fat.

The best treatment for Mitochondria functionality is zone 2 training. It has the biggest improvement in fat burning and lactose clearing capacity.

Exercise alone can work without diet in losing weight if you train the mitochondria to be more efficient.

Zone 2 training protocol

 

3 times 60-90 minutes per week at low intensity (being able to converse)

Or

40 mins cool down after the intense workout.

TRAINING ZONES 

 

ZONE 1 TRAINING

  • Minimum stimulation of muscle using fat for energy.
  • walking upstairs
  • Jog for fitter person
  • 7 minute mile for an athlete

ZONE 2 TRAINING

  • Exercise intensity that uses the highest amount of fat before utilising glucose.
  • Slow twitch muscle fibres only

ZONE 3 TRAINING

  • Transition zone
  • Fast twitch muscle fibres convert fuel into lactate for the slow twitch to use

ZONE 4 TRAINING 

  • Zero fat oxidation for energy
  • Lactate threshold before burning out
  • Max power for 60 mins

ZONE 5 TRAINING

  • Utilising lactate only as fuel
  • Zero oxygen muscle uptake
  • Short bursts of max heart rates

Ingredients 1 tsp smoked paprika 1 tsp ground cumin 1 tsp dried oregano leaves 1/4 tsp dried c hilli flakes 2 (about 500g) chicken breast fillets, halved horizontally 1 tbsp extra virgin olive oil 2 small zucchini, sliced 175g mini capsicums, deseeded, halved 1 tbsp no-added-salt tomato paste 400g can cherry tomatoes 2 tsp white balsamic condiment 140g (2/3 cup) wholemeal couscous 160ml (2⁄3 cup) boiling water 250g green beans, steamed, halved lengthways Lime wedges, to serve Instructions Step 1 Combine paprika, cumin, oregano and chilli. Sprinkle spice mixture over the chicken. Step 2 Heat half the oil in a large non-stick frying pan over high heat. Cook the zucchini for 1-2 minutes each side or until golden. Transfer to plate. Add chicken to pan and cook for 2-3 minutes each side or until browned and almost cooked through. Transfer to a plate. Step 3 Heat remaining oil in pan over medium heat. Add capsicum. Cook, stirring, for 2 minutes or until begins to soften. Stir through tomato paste. Add tomatoes and 125ml (1 ⁄2 cup) water. Bring to the boil. Reduce heat to low. Simmer for 6-7 minutes or until slightly reduced. Add chicken, zucchini and balsamic. Simmer for 5 minutes or until chicken is cooked through. Step 4 Meanwhile, combine the couscous and boiling water in a heatproof bowl. Cover and set aside for 3-4 minutes to absorb. Fluff with a fork.

Salmon & Quinoa Bowls with Green Beans, Olives & Feta

By Zina Stone • November 13, 2025
Ingredients 450g salmon fillet ½ teaspoon salt, divided ¼ teaspoon ground pepper 30g string beans (green, yellow, or a mix), trimmed and cut into 1-inch pieces 1 ¾ cups water ¾ cup quinoa (red, white, or tricolored), rinsed 3 tablespoons lemon juice 2 tablespoons olive oil 1 clove garlic, minced 2 teaspoons chopped fresh oregano, plus more for garnish, or 1/2 tsp. dried 1 medium tomato, seeded and chopped ¼ cup crumbled feta cheese ¼ cup pitted Kalamata olives, halved or sliced Instructions Preheat oven to 400 degrees F. Line a large baking sheet with foil. Place salmon filet on the prepared baking sheet and sprinkle with 1/8 tsp. salt and pepper. Bake until the salmon is no longer opaque in the center and flakes easily with a fork, 20 to 25 minutes. Let rest for 5 minutes, then flake the salmon into bite-size pieces (discard the skin). Meanwhile, bring 1 inch of water to a boil in a medium saucepan fitted with a steamer basket. Add 8 ounces beans; cover and cook until tender-crisp, about 5 minutes. Rinse the beans under cold water, drain well, and set aside. Combine 1 ¾ water, ¾ quinoa, and 1/8 tsp. salt in the saucepan; bring to a boil. Reduce heat to low, cover, and simmer until the quinoa is tender and most of the liquid has been absorbed, 15 to 20 minutes. Fluff with a fork. Whisk 3 tablespoons lemon juice, 2 tablespoons oil, 1 clove minced garlic, 2 teaspoons chopped oregano, and the remaining 1/4 tsp. salt in a small bowl. To serve, divide the quinoa among 4 dinner bowls. Arrange the salmon, beans, tomato, feta, and olives over the quinoa. Drizzle with the dressing and garnish with more fresh oregano, if desired.
