The two most important factors to getting the most out of this Pull up Dip Station Routine is getting the level of resistance right and making sure not to rush. If you perform the repetitions too fast you will most likely be using bad form which means less muscle development and you also increase your risk of injury.
If you move from exercise to exercise too fast you may become too fatigued to execute maximum intensity with each set. If you find that the number of repetition you can do begins to drop off dramatically you are going to fast. Take a break or includes some sit-ups, body weight squats or lunges in between the upper body exercises that way you are still keeping your heart rate up but you are giving your arms, chest and back muscles time to recover more completely.
