Gaining 40lb of muscle by summer time is not a reasonable goal. If you ate a ridiculous amount of calories you could maybe gain that much but you'd be pretty chunky. I think if you gained 10lb of lean mass by summer you'd be doing very well. Also, I think you're going to have to hit up a real gym or invest in some good old fashion bars and weights.

You definately need to read all the stickies as suggested.
