Yoga as exercise is a physical activity consisting mainly of postures (asanas), often connected by flowing sequences called vinyasas, sometimes accompanied by rhythmic breathing (pranayama), and often ending with relaxation (lying down in savasana) or meditation.
Resistance training is a form of exercise that improves muscular strength and endurance. During a resistance training workout, you move your limbs against resistance provided by your body weight, gravity, bands, weighted bars or dumbbells. Some exercise machines can also be used for resistance training.
Movement exercise works to strengthen the complete system, working your muscles through a deeper range of motion. In this way you are not just training to increase strength in your bench press, but also to increase strength through a more complete range of motion.
