Anaerobic training, including weight training, weight machine use, and resistance band workouts. Resistance training will increase your strength, muscular endurance, and muscle size; running and jogging will not do that.
Resistance training has two different, sometimes confused meanings - a more broad meaning that refers to any training that uses a resistance to the force of muscular contraction (better termed strength training), and elastic or hydraulic resistance, which refers to a specific type of strength training that uses elastic or hydraulic tension to provide this resistance. This article discusses the more limited definition, of elastic/hydraulic resistance training.
