im trying to loose body fat and cut in

i am a freelance fitness instructor so need to do the spinn, all weights at 12-14 reps.

training mon. 10.30 spinn class,chest and tri, 6pm spinn class
tues. shoulders and abbs
wed. 10.30 spinn, back bicepts, 6pm spinn
thurs. rest day
friday. 10.30 spinn, chest and tri, 6pm spinn class
sat. shoulders, core and legs
sun. rest/ active recovery eg light weights all over body workout

the weights move forward each week so one workout only gets done once ie this week it is back then the next week it will be done twice then shoulders will be rested and only trainned once that week.
