The first thing you need is a well-built cardiovascular system to let you train at significance full level from the beginning of your workout until the end. You must not train to jump higher each day of the week but when you do workout you desire to obtain the most out of it. Squats, with or without weights are also excellent to improve the muscles used when trying to jump higher in basketball. Keep in mind never do any weight training without a spotter and the correct equipment such as a weight lifting belt to hold your back.
