Shadow Boxing Workout App funktioniert nicht

This boxing app features multiple pre-made intense shadow boxing & punching bag workout sessions.  You can also create your custom shadow boxing training sessions and custom HIIT workouts.  Finally you can even mute all audio coaching if you only want to listen to your intense boxing workout playlist!  You can easily pick how much time you have ahead of you, the exercises you'd like to do, the intensity and start your boxing workout!  You can also add additional calisthenics exercises like push-ups, burpees, mountain climbers, squats or sit-ups in between boxing rounds!  If you box, this is a great way to keep improving, and if you don't it's a cool alternative way to work out and do boxing drills!  You can use our pre-made timer modes to quickly set the rules from boxing, MMA, muay thaï, kick boxing or amateur boxing.  Try existing training sessions or build your own workouts using the various exercises and settings.  Use this boxing app for your training and improve your skills from home or the gym, like a virtual boxing coach!  Boxing alone can get demotivating and this is a great way to stay motivated while working out.  This is the perfect way to match what kind of fitness regimen you want to follow at home, like a 7 minute workout or something closer to boxercise.  For instance "20 minutes HIIT" is a very high intensity interval workout to burn a lot of calories and have fun... but you can find simpler ones to get started!  You don't need any equipment to complete the various trainings and various drills, but if you have a punching bag or a jump rope at home you'll be able to use them. - REPETITIONS gives you one combo to practice for an entire round.  Use the free timer for your sparring sessions, training or heavy bag workouts.  This can get intense, but it's a great fitness exercise and will help with cardio and burning calories.  This will help you focus on your fitness target, weight loss or performance improvements.
