I am a hard gainer and trying to bulk...Does it make sense to take whey protien on an off day even though my muscles arent in an anabloic state?
Consume a lot of protein. 1g of protein per pound of your body weight. Don't just count the protein from your shakes, though. Count the protein from other beverages and foods you consume throughout the day. Your body will tell you if you've had way too much protein, as I've heard consuming too much can make you shyt.
Look into some different protein blends, such as Isogainer. Also, search the Recipes forum. Look for homemade weight-gainer recipes, as they're more effective and healthier than store-bought blends.
Your muscles will be in an anabolic state for over a week after a hard workout... They are just the MOST anabolic in the hours and days right after a workout. It tapers off slowly after a workout.
Keep eating a lot of protein all the time. In fact, since you are hardgainer keep eating a lot of food in general, all the time.
Almost all hardgainers I have met didn't eat nearly as much as they thought they did.
Best advice right there. Keep eating what you see thats has some nutritional value (ie. wheat pasta over chocolate cake. Lots of carbs and cals, but the pasta is better) My friends in the same situation. He's only 124lbs. He buys his own mini frig. and buys milk, bagels and yogurt and turkey. He says he is eating "a lot", but the food is still in there from 3 days ago, meaning he does eat more than before, but it is still not enough.
The best thing you should do is go make a fitday.com account. My weight/lifts/overall size went up when I did.
Track all your food and make sure your eating above 4,000kcals. It all depends on your BSM though. For me, a Mesmomorph, I need roughly 4,000kcals to see some growth. Everyone is different though. Find what works for you.
