Many alternatives available to train your back, but these two are my favorite and the most I often do :
DUMBELL ROWING
I've been a low carb dieter for one year but the flexible one even when the time my goal was to lose weight.
Im a shooting star leaping through the sky
Like a tiger defying the laws of gravity
Im a racing car passing by like lady godiva
Im gonna go go go
Theres no stopping me.........................
Secondly, make your own photo of before and after. Thirdly, keep track of your waist measurement instead of your weight. Fourthly, reward yourself by body treatment not with food.
Just for a reminder, if don't have a date by Valentine's day at least you boost your fitness level and confidence. If Valentine is about love then let's celebrate Valentine by loving your body and health. Good luck with the challenge!
