Workout for the 60 old woman can be the challenging one. I think after proper consultation only a senior person should opt for before going for the workout.
For the fitness of old age women, it is essential to consult and have advice from one of the reputed and trained fitness center, as they can only judge old body in much better form.
I agree with Christine on adding in balance and flexibility work to your current program. You already have a great program and if you enjoy it keep it up.
You could try adding yoga or pilates to get in the balance, flexibility and core work Christine talked about. You may find the change in modality to be a nice addition to your programming as well.
It sounds like you have a great program started for yourself, so congratulations! Rather than give you a specific routine (without knowing your specific goals/limitations), I will give you a few suggestions. I agree that the cardio and strength components are important to your routine. Cardio is wonderful for your heart and for reducing the risks of many diseases. The strength training exercises will help with bone density, which is especially important for women and lowering the risk of osteoporosis as we age. It also builds muscle which keeps your metabolism higher.
In addition to your current program, I would add a component that focuses on core strength. Abs, back, hip stability, and glutes. All of these muscles play a role in supporting the spine which is important for everyone.
Also, balance and flexibility are also important to your program. Some of the core work will help with balance. The flexibility/stretching will help keep your joints moving freely, increase your range of motion while doing your exercises, and reduce your risk of injury.
Keep going with your program, and find different activities that you enjoy!
