I am an avid distance runner who has gone through a long period of high mileage, losing lots of muscle and fat (though there wasn't much to lose). I have gotten down to under 3% (my caliper readings are 3, 4, 3 for pec, abs, leg). This low body fat seems to have contributed to my current injuries, so I have taken a hiatus from running for now until I am healthy.
I am 5'6", 106-107 lbs, and I would like to gain some weight back. However, I want to gain muscle as well as a little fat. I have worked out 2 days on (bi's/tri's & chest/back), 1 day off for the last two weeks, and have upped my food intake considerably (at least 2300-2500) but still haven't made any weight progress. I notice that I feel more toned and better about myself, though - but thats just not gonna cut it .
I have a fast metabolism genetically (my dad is 42 and has never been over 6% body fat) and I seem to almost fidget off or radiate my calories...every time I overeat I notive I get warm and my heart is beating faster for a while after the meal. Also, I am in college so I guess I do a fair amount of walking or biking.
Basically, do I just begin to eat even more? Do I need more rest because of my body type? 2500 calories seems like a lot for someone my size, and I'm already having trouble eating that much.
Thanks for your suggestions.
