Welcome to the ’AstraTC‘ app, which can help you effectively train your pull-ups. You can set the number of pull-ups and the speed of voice broadcast through the app, making your training more regular.\nPull-ups, sometimes referred to as chin-ups, are a type of resistance exercise that rely on the user's own strength to overcome their own weight and perform upward work.
