Respect your body. Listen to your body and decide if you need to rest, or push for more.
Do what you body is able to do, Do not overdo it: your body is not designed to be a superhero body.
Don't compare yourself to other people whether they're skinny or bulked up. They may or may not be healthy. Rather, focus on yourself only.
Eat a lot of whole green foods to support your body when working out.
Choose safety over pride.
Drink adequate pure water before and after your workouts; no energy drinks, Gatorade, or other artificial drinks should be consumed.. Coconut water is highly recommended.
Stretch, stretch, and stretch more. Especially, after workouts.

Some people like to run daily or to rotate through different exercise types; others like to do the trendiest workout. It doesn't matter if you exercise at home or go to the gym, as long as you are doing something to build the strength of your heart and muscles
