I regularly do some exercises to improve my figure and to be in a good form.
It requires my will and endurance.
But the result is worth it !
I start my training session with a warm-up and don't forget about a stretch at the end.
These simple things help me develop my muscles and be healthy.
I always try not to overeat and I always try to eat healthy food.
One more thing that is very important, to my mind, is sleeping enough.
I am used to sleep not less than 7 or 8 hours.
So, in my opinion, if you have enough sleeping, proper eating and regular physical exercises, you become energetic and keep your body fit and feel fine and happy!
