Jogging. Fuck the rest of opinions here. >>2 is wrong because it's wrong to repeat an exercise daily (don't give time for your muscles to repair). >>3 is wrong because boddyrock is stupid. >>4 is completely retarded.

Start jogging. Move your ass and jog 3-4 times a week. What you need to do is find some nice place you can jog (like a beach or a stadium or a long road), and also find some imaginary spot that will be considered 1 lap. Then you'll do as many laps as you think you can do without getting too much tired. Repeat that many laps through the month. Next month go for more laps. Et cetera.

If you want to get an athletic-but-feminine body it's all about the mentality (and most girls suck at this part). Also look up shin splints, which you want to avoid. Do warm up before and most importantly, after jogging. Don't pseudo-jog like I've seen some people do, keep a pace that is faster than your walking.

Your jogging is going to increase your appetite. Stay away from sugar and junk food. If you don't know how to cook it's time to learn. Eat lots of fruit. (my advice doesn't contain a contradiction, I know that fruit also have sugar)

Research everything in my post to get better ideas. You don't need any sort of equipment to do this by the way. You can also watch some Bruce Lee films (works for me!)

Girl, there's a 99% chance you'll lister to the bullshit of others and not me, but I am the real truth.
