If you're new to exercise, you need all the support and encouragement you can get. Be sure to set up your "team" that will be there for you when you need them. My team is mostly my family (including my very athletic son-in-law Tino) and those who surround me at the gym.
Tell them what your intentions are and what you need support in. Just be honest with them. A lot of them want to support you and the goals you've set for yourself.
Don't go through the journey by yourself.
Have a blessed day!
