Hello I am 17 years of age and I weigh 49kg and im 5ft1 :) I run a mile and half in 10.30 which is about a 7minute mile.. Ive been trying to get better, so recently Ive been doing a minimum of 2hours cardio a day which involves cycling 12-16miles and running for 90minutes uphills.. and I have been weight lifting, 200 reps of Bicep curls, tricep dips, sit ups, squats and push ups.. but my weight isnt dropping ive been doing this for 2weeks, oh and also do 1hour of boxing 3times a week.. any tips? I haven't started eating healthy yet but no more than 2500 calories, which my body needs cos the exercise .. help?xx
