When it comes to strength training, I would recommend getting one on one guidance, because there exists the risk of injury if you don't know how to do it properly. Having said that, I don't really know any websites that do a complete routine, but if you know what you want to accomplish, you might do a search that's more specific, like Googling "strengthen shoulder muscles" or "how to do squats".
If you have a Netflix account, they have
The 10-Minute Solution: Target Toning for Beginners available on instant play.
I found a book that is very helpful is
The New Rules of Lifting for Women. You can get it at the library, or buy one from Amazon, even used, for pretty cheap.
I love working with free weights. It's a more effective workout than machines, but if you're not doing it properly, then you risk injury and time out from the workouts. I had to lay off work on my arms for several months due to a shoulder injury and also had to modify exercises for bad knees.
