Hello there,
Being 5"5 and only around 114lbs, I'm slightly underweight and may need to put on a bit of size. I'm an ectomorph and don't have a large frame so I might be okay but I've been wondering if being underweight (although only slightly, I think BMI is around 18) could be hindering my strength potential and if I might be better off with around 10-15lbs extra muscle.
I don't want to go on a bodybuilder type programme and don't want to compromise my strength gains or stop doing gymnastics training. Currently with most of my exercises I do 2 sets of 3-5 reps and don't train till failure. As for calories, I currently eat at maintenance level according to my daily acivity level. If it's a heavy day of training I eat a lot more but when I'm resting my calories come down. If I increased my calories to above maintenance, would this be enough to trigger some hypertrophy or would I need to change my training too? I'm fairly lean but am also worried I might put on fat instead of muscle.
