Am I doing enough Cardio and/or Weight Training??

at 115 you likely dont have much to lose. how long have you been on this program. i am assuming you are trying to get toned, so results will take you a couple of months and that will include paying strict attention to your diet. to really tone up and improve definition you have to reduce your bodyfat which is diet specific. are you squatting? i try to keep the protein at .75 - 1 gram of protein/lb of bodyweight. again, you will need to keep good stats on your diet.

if you are seeing small results keep going for a while, play with your diet a bit if thats not spot on and give yourself a couple solid months of consistency in both training and diet and see how you look. it sounds like you just need a few tweaks and not an overhaul. leg results = squats or lunges abs = diet to see the muscle and then ab exercises to make the abs sharper... keep the weight as heavy as you can handle and still complete your sets and once thats easy add weight.

my 2 cents... good luck..
