1 If you're a beginner, start with 3 to 4 days of the cardio exercise of your choice, working at a level you can handle. 2  Add time each week to work your way up to 30 to 45 minutes of continuous exercise.  As you get stronger, try interval training once a week to help boost endurance and burn more calories.
Instructions: 1  Add thawed Ahi Tuna Steaks to medium hot fry pan (thatâs been greased with extra virgin olive oil) 2  Add salt, pepper, and lemon pepper to Ahi Tuna Steak while itâs cooking. 3  Rub in a little bit of extra virgin olive oil.  Cook for 3 minutes on each side for medium rare. Add one minute for medium.
Heat the pan on the stove for about two minutes or until it reaches medium to high heat. Gently lay each tuna steak on the hot griddle pan. Let the fish sizzle and don't move it around in the pan. Cook for only 2 minutes on the first side for a rare steak, or 5 minutes for a medium.ne-inch thick tuna steaks can be perfectly cooked in about 10 minutes. Much like a good sirloin or quality beef steak, tuna suits grilling or shallow frying in very hot oil. Use a marinade for extra moisture and to add flavor to the fish.
