I certainly would never advise a client to do any cardio before a weight training session, as aside from the obvious, you will need to save your energy for the task at hand â lifting as much weight as possible with as much intensity as possible. Cardio after a weight session is far more beneficial.
How to Bake Tuna Steaks. 1  Preheat the oven to 450 degrees F. Place tuna steaks on a greased baking sheet in a single layer. 2  Bake for 4 to 6 minutes per 1/2-inch thickness of fish or until fish begins to flake when tested with a fork but is still pink in the center.
Cook time is heavily dependent on the thickness of the tuna steak, but lets assume it's an inch and a half in thickness. Heat a pan with 1tbsp of vegetable oil over med-high heat. Once hot, add the tuna to the pan and cook for 1 minute then flip. You'll notice the color of the tuna changing quickly to an ivory. Keep flipping the tuna steak until the raw color has completely disappeared from the edges. Remove from the pan, and let it sit for a couple of minutes.
