[~One Of A Kind~]

Ok, so i've finally decided to plan my exercise routine to get myself moving more frequently. I'm planning on doing 30 crunches, side crunches and push-ups. Also, i'm doing 20 dips and curls to work on my arm muscles, since they're really weak. 20 kicks (leg extensions), 3 sets of 15 squats and 5 mins of jump rope. All with a slight rest in between. i'm planning on doing this twice a day, with a few hours interval. It kinda sounds a lot but it really isn't. Is this routine ok for a 14 year old girl who's relatively fit? SUGGESTIONS PLEASE!!! thanks
i'm not going for body building. I've noticed i've gotten slightly fatter (though that does NOT mean i'm fat) and i just want to be fitter and have fun in the progress!
