Cardio exercise is an exercise that raises your heart rate. Face it our bodies were made to move. And we all know that to keep our muscles in shape we need to move them. This movement makes them stronger and stronger muscles make for a more efficient and healthy body. Your heart is a muscle. Therefore working it makes it stronger. A stronger cardiovascular system means more capillaries delivering more oxygen to cells in your muscles. This enables your cells to burn fatter during both exercise and inactivity.
Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles. When properly performed, strength training can provide significant functional benefits and improvement in overall health and well-being, including increased bone, muscle, tendon and ligament strength, and toughness, improved joint function, reduced potential for injury, increased bone density, increased metabolism, improved cardiac function, and elevated HDL ("good") cholesterol.
