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.
Sear the tuna steaks. Add the fish to the hot oil in the pan and cook for 6 to 9 minutes. The steaks should start to sizzle as soon as you add them. If they do not, take them out of the pan and allow the oil to continue heating. You need the oil to be hot enough to sear the tuna, trapping the moisture inside.
