the soreness you are feeling is normal, laughin. Your muscles are healing and as you keep up your routine you will find that the degree of stiffness you feel following a workout will mimimize/become non-existent. (that is until you significantly increase plate load/add a variation to your routine).
Drink lots of water. Cut all the crap out of your diet. This is no joke. I have now dropped 14 pounds of unwanted weight which I gained from drinking 2L of coca cola almost daily. As women, thighs are one of the places you will start to see jiggle. Personally I only drink water now, or natural fruit smoothies. Cardio 30 mins in the morning, weight training later in the day. On off days, 45 mins-1 hour cardio.
I have no jiggle left on my thighs. Yes it can be done. I reached my goal weight in about 2 months and have no plans on going back to the way I was eating before. For my thighs/bum, I do leg extensions, not overly heavy, (for now maximum 45lbs.), squats, lunges, abductor/adductor machine, good mornings, deadlifts (variations), and I run stairs and jog.
Thats my suggestion to you, because it worked for me.
Good luck!
