Here's message I recently wrote to a fellow member who found it helpful. I wanted to share it with others:
Saw your post about tips in gaining weight. My story seems pretty similar to yours in how low of a weight that I started. Anyway, here are some tips.
Always remember that calories ARE KING. If you don't have enough food to grow.... you won't. An easy way to calculate the calories you need would be to multiply your body weight by 15 and then add about 500-750 calories to that a day. If you can eat a little more, do it! The trick here is that you want "Clean" calories. Here's a 12 week mass gaining program that is pretty good. It includes diet and nutrition. Even if you just did the nutritional part of this program you would be doing good. http://www.bodybuilding.com/guides/male-20to39-muscle-building/nutrition For your workouts... I would recommend a traditional bodybuilder routine to be honest. I will show you the workout I'm about to switch to below. However, important to remember to get enough sleep (that means 8 hours). Big ass compound lifts are the key to mass... these are squat, deadlift, and bench press. They will help give you an edge over any other activity. Here's the link of what I am starting, I am pretty stoked about it: http://www.bodybuilding.com/fun/growth-spurt-30-pounds-muscle-in-one-year.html
When it comes to calories, it can be hard to push that much down your throat. I know that. I don't know how many times I've felt like I was going to puke from eating so much. But, there's some good news. Once you eat a giant amount of calories for a few days in a row, your body expects it and it's not that hard. Also, weight gaining shakes (expensive but worth it) can help you get those extra calories. I'm starting "Serious Mass" by ON today.
I aim to inspire people (I saw that you do to). Let me know if I can help in any way. I think I'm going to start posting videos on youtube with supplement reviews and some workout stuff.
Live with passion,
