At least until you get into a routine and better understand how your body reacts. From there you can create your own routine to better fit your needs or you can continue to find new routines through the website. I've heard it is a good idea to switch up your routine every 4-6 weeks. If your looking to build muscle lift heavy with low reps. Looking to tone lift light with high reps. Make sure you throw in cardio for toning. Less cardio if your looking to build. Healthy eating always a must. All of this seems overwhelming but if you slowly work into it, it becomes habit. A little patience and a lot of dedication ;-) 

You'll do great!!
