with the amount of cardio your doing if your not getting enough protein your going to be catabolic all the time... meaning all those resistance exercises are a waste because your not building any muscle... make sure your getting enough protein from whole foods and supps
your doing too many different exercises (as Birds has stated) simplify and look at making consistent progress in weight and reps
your doing a huge amount in the gym on a weekly basis... too much... I would ditch the cardio machines... they're a waste of time
ditch those scales, they're garbage
you do too much direct ab work and not enough posterior chain work... crunches don't give you abs, they just shorten your hip flexors and give you back pain
the basis of an athletic physique is a strong butt and back
girls typically can't handle as much upper body frequency or intensity as guys but they can handle as much if not more lower body volume
if I were you I'd squat twice a week at least... a heavy day, low reps and a light day, high reps... mixed in with the lunges and a few other lower body movements your already doing... a challenging high rep squat/lower body workout will burn more calories than any abcoreblaster class
if you want to circuit train, kettlebells, medicine balls, sprints and jumps are as good as it gets
I'd only deadlift once every week or even two weeks... it should be hard and heavy enough that your pretty much fried afterwards
you don't need to run on your off day... foam rolling, stretching and mobility work is better
just my 2c... train like an athlete, get stronger, faster and have more stamina... and as a bonus you might end up looking like one... seen some of the Olympic track and field girls!
