1,500

iam 18yrs old

i work out (hard) for 45mins 4X a week, all the other days i do yoga, horse riding, biking, walking.

i want to be 125lbs - 130lbs

so what do you guys think?
i am open to any other suggestions, comments

There is no set calorie range, it all varies by our size, age, etc.

Best thing to do is get a rough estimate and then see where you fall in with activity.

I personally like the Harris Benedict Formula for ease and general figuring. From there adjust as you need for your activity and body.
