i just dont feel comfortable. i feel like i look horrible in it ! i really need help !Summers right around the corner and we want to look good in bikinis, have any advice to get in better shape?
depends on what parts need more work, alot of girls ride on a stationary bike, sitting while peddling for a while and then standing while peddling, really tones the legs! running or fast paced walking maybe. abs is like 90% weight loss and 10% workout so if you do alot of set ups and not lose any weight or gain weight it will be hard to see definition. eat more small meals every 2 hrs or so.DON'T STARVE YOURSELF! Eat your carbs early in the day and not at night . water!water! hope this helped a little
