Abs were made in the kitchen not in the gym

True but, that six pack isn't going to make itself. Exercise is incredibly important to a healthy life. From age 40 on we begin to lose 1 to 2% of our muscle every year so we tend to lose strength. Think about how critical strength is healthy aging. The more weight and strength you put on bone the more it grows. physical activity is a tremendous way to maintain bone strength additionally exercise helps lower anxiety and stress levels it's a good treatment for depression that helps you feel energized and pressure sleep also maybe one of the important thing for preventing dementia and Alzheimer's disease. Exercise is not a cure-all for weight loss, in order to lose weight you have to eat less and exercise more however there is something about physical activity that almost preferentially makes belly fat disappear that's why you may notice that your clothes fit differently but your scale hasn't changed.
Try to get 150 minutes week of brisk walking or if you like to run about 75 minutes per week on top of that try to do two days week of strength training in addition to that you should probably try to do some sort of stretching like yoga.
But if you're like me it's hard to fit it in. I try to workout in the morning because by the end of the day I just don't want to. And I've tried it all: set the alarm extra early, slept in my running clothes, called a buddy... And it's all failed. I gnash my teeth at running and strength training and have too short of an attention span for yoga and yet I do it. The first 5-10 minutes of running I make deals with myself: run to the tree, to the next bush then to the fence. But by the time I get halfway thru I'm ok, I'm warmed up and my endorphins are moving and then I struggle thru the required stretching. My body has a painful way of reminding when I'm not keeping up with my strength training. So I make it a priority and continually recommitted to my health and my body. So you can feel sore tomorrow or you can feel sorry tomorrow but only one of is going to get your those abs.
