I'm not the female ofcourse.. This is a question for my lady..

Well she just gave birth about 4 months ago & she wants to loose weight & get back in shape.
She's now 5.1 in / 150lb / 32 age.

she started the gym back up again and she's been asking me if I can get her something to loose weight but not sure what for a female!
She use to get these shots from a doc before she gave birth (the famous b12 shots) & she got in shape with these shots.
what can you recomend for a female besides those b12 shots?
