How adequate is my exercise regime?

CW 156lbs

If I eat 1200 cals a day (as MFP recommends) and do the following exercise regime (it's the max I can fit it with looking after my son and working long hours), do you think this is enough? I want to reach my goal by end June so roughly 24 weeks.

Mon - Body Pump
Wed - Outside Jog
Fri - Body Attack

Thanks
