br br The F4X training system shows it all! Example: People on low fat diets look drawn, gaunt, and weak. They are often sick, sometimes to the point of literally breaking down. And, they can never just enjoy eating out. Every meal and every gram must be accounted for. Do you really think this will make you fit? Of course not... it will worry you to death if it doesn't kill you first! br br To exercise the correct way takes a trainer that know what they are doing. Cardio is a good way to start but caution needs to be in order. Start slow and work up to good routines that you can do at least 3 times per week. br br br br Photos by: freedigitalphotos.
