Trying to create my own workout plan

I am very new to fb and loving it so far. As much as I would like to purchase a program to support them, I joined a gym this year and really need to budget.

I am planning to create my own workout plan and wanted some feedback from you guys. I was planning on working out 4-5 days and here was what I was thinking. I could do: upper body and core, cardio or hiit, lower body and the other 2 days could be recovery stretching days or yoga days. I could also go for spin classes in my gym for the cardio portion.

If I get some results with these videos then I might consider getting a program. Thanks guys
