Ok so I've been working out with weights trying to build muscle and tone up but I'm having a problem building muscle in the back of my thighs heeeeeelp..... (U can c in the last pic I posted)
Reducing fat builds muscle, are u in your hypertrophy phase or muscle endurance phase?
Squats, lunges and dead lifts.
You could also look at adding sone Olympic lifts(power cleans)but be cautious of your form. Plus remember it will take 6 to 8 weeks for true muscle development
