Depending on what you are working on, setting your bag to different heights can be a welcome challenge. When you are starting out, you should adjust your speed bag to face level. If you want to get some extra burn in your shoulder muscles (traps and deltoids), raise your speed bag an inch or two higher and challenge yourself on a whole new level. This technique can also help a boxer who has a habit of dropping their hands when they start to get tired when sparring. With the extra shoulder strength from training with a higher bag, you’ll find it easier to keep your gloves at the proper height when training for long periods of time.
