You may not think about it this way, but getting sufficient sleep is a crucial part of your fitness routine. (After all, the real gains happen when you're resting!)
The Mayo Clinic warns that extended sitting can increase your risk of excessive blood sugar, abdominal fat, bad cholesterol, and high blood pressure.
Unless you're Danny Glover, never say "I'm too old." Instead of believing you're young, you'll hunt for evidence that you're "too old." Working out reinforces this.
When you remark, "I don't have time," it's like saying, "My dog ate my homework." Sometimes it's deeper—poor self-esteem, traumas, fear of failure, etc.
After 40, college workouts and diets won't help you get in shape. Following an old strategy can overwhelm, stress, and injure your health.
If you've said, "I know what I need to do, I just need to do it," you don't. (You would have done it already!) You can admit you don't know how to get fit.
Gym-going clients please trainers. We appreciate when our clients use their fitness gains to live full, active lives instead of just sitting on the couch.
