Do you give up before you even start? Here are two things you can try:
1. Do something you enjoy. Too often we try to do something that's disagreeable to us. That's a sure recipe for disaster. If you don't enjoy doing it, you won't persist!
2. Think back to all the times when you didn't quit and were the better for it. I've never regretted the times I did not quit. I'm glad I stuck with it. You will too! A personal example is strength training. I became serious about this sport about 2 years ago. I've stuck with it because I really enjoy it!
By the way, I had a monster workout today, beginning with stretching.
That was followed by three of my all-time favorite upper body exercises:
The standing dumbbell curl.
The pull up.
And the lat pulldown.
I know some of my readers have probably tried weight training in the past and have had bad experiences with it. I want to reiterate that you don't have to do anything I do. You can go heavier or lighter. You can work out at home instead of at the gym. You can hire a personal trainer to help you or you can work independently. Once you're happy with what you're doing, keep at it!
Have a wonderful day!
