Food is 80%, exercise is 20%. I am loving exercising. I can tell you what I do, what is important to me - it may work but really it's about what makes you comfortable.
I have learned to love the gym. I found a gym that has fantastic equipment, classes, variety of hours, classes and a very positive atmosphere.
Ensure you know how to use the equipment and correct form. If you can, invest in a trainer to help you - it's an expense that I have never regretted and has been instrumental for me.
I plan out my sessions in a small book that I take with me to the gym. I track all the exercises, how many reps/sets and weight used. I change the program every 3 weeks to shock my body before it gets too used to the program. It's good to see that I increased my reps, sets and/or weights - and is a great sense of empowerment to keep going.
For my body type (pear), I need to do quite a bit of cardio. I don't like cardio (I prefer weights) so I warm up with about 30 min on the elliptical with interval training - 1 min go super hard, 1 min a bit slower, then 1 min forward, 1 min backward, etc - always switching it up. Then I work on weights. I do chest, arms and abs (1 X per week), complete lower body (2 X per week), back, arms and shoulders (1 X per week) and then one day with a full body program. I end with another 20-30 min of cardio.
Not sure if that helped, but key things - plan for your exercise, track it and change it up whether you are working at the gym or at home
