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.
Add the tuna steaks to the pan once the oil is fully heated and sear for about 2 to 4 minutes per side. Tuna steaks typically are between 1- to 1 1/2-inches thick.Searing the steaks for 2 to 4 minutes leaves the steaks done to rare or medium-rare.
