MensFitness.com has low down on some surprise foods that can help you build muscle. MF also fills you in on how to prep the muscle foods, as well as properly cook them.

1. CLAMS
Why they’re good for you: Clams are loaded with iron and are one of the few meats high in vitamin C — one serving contains nearly half of your recommended daily intake.
Prep: None needed. Just toss the shells on the grill.
How to cook ’em: Grill over high heat until they pop open.

2. LOBSTER
Why it’s good for you: In or out of the shell, lobster meat is significantly lower in fat than pork and beef, with a healthy dose of calcium.
Prep: While the lobster is still alive, cut it in half lengthwise, drain and reserve the juices, and brush with olive oil or butter.
How to cook it: Place the cut side down on a very hot grill for 3 minutes, then flip and pour the juice over the top; grill for another 4-5 minutes. The heat caramelizes the meat, giving it more flavor.

3. VENISON
Why it’s good for you: Deer meat has fewer calories than chicken breast and twice as much iron as beef.
Prep: Marinate in red wine or olive oil before grilling.
How to cook it: Lean meats are best cooked to medium rare, so 3 to 4 minutes per side over high heat.

4. OSTRICH
Why it’s good for you: This long-necked beast is very lean and contains a large amount of iron.
Prep: Drizzle with or marinate in olive oil. Since the meat is lean like venison, it needs added fat to stay moist.
How to cook it: Grill over high heat, allowing the meat to cook for 3 to 4 minutes per side.

5. SWORDFISH
Why it’s good for you: Besides being the ultimate sailing trophy, swordfish has virtually the same number of calories per serving as chicken or beef, and it’s loaded with heart-healthy omega-3 fats.
Prep: Brush with olive oil and top with a squirt of fresh lemon juice.
How to cook it: Just like ostrich. Grill over high heat for 3 to 4 minutes per side.
