Work with her make it a team thing..be sensitive that she might be self conscious about her weight or going to the gym(women often are)be supportive..those are the main things to keep her going..
As far as training iam sure the ladies could give better advice but not knowing her level of fitness..start small,planks 2min*2 doesn’t seem like much but that’s a tough 2min for most..I would keep her with machines and body weight help her with form..
Body weight squats 3 sets 20 then one to failure
Push ups same thing have her do modified if regular is too hard
And assisted pull ups
Obviously cardio is a must
And of course the most important thing
Diet, you know?its 75 percent she can’t be eating pastry and expect to lose weight and live a healthy life..spiking Insulin hard in the morning also makes me hungrier all day..
Have her switch to a smoothie keep her protein high to reduce catabolism and encourage multiple healthy snacks (almonds,protein bar)
And Whole Foods try to eat a healthy dinner together..with your encouragement and not being too negative.she should gain affinity for training the same way you do
