Because Skipping is Cardio
Cardio has been thought to be the arch enemy of muscle growth, but the right kind of cardio can help muscle growth by increasing blood circulation and improving anaerobic performance.
Skipping Improves Workout Performance. You have less Light Headedness, less Nausea and less Fatigue.
Skipping improves your energy performance and endurance. This is why boxers skip; so that they can perform at the highest intensity for prolonged periods of time. The reason why people often experience light headedness, nausea and fatigue or feeling exhausted when doing squats, for example, is because they are not used to expending so much energy in a short period of time. The body is therefore trying to cope with the energy-intensive part of the workout instead of the muscular stress. When your body is more adapted to working at a higher intensity, you will feel less of these side effects.
Focus on Muscular Fatigue Instead of Cardio-Vascular Fatigue
Ever had to stop squats or deadlifts because you feel light-headed or nauseous? What if you didn't get that feeling at all and could carry on until your muscles failed, instead of your energy system? Skipping makes your body more adept at high exercise intensities, so that when you train under the iron, you can focus on delivering maximum stimulus to your muscle without hindered energy limitations.
Because of the above, when your body is more cardio-capable, recovery after your workouts will be quicker and more efficient. Your body will need to recover less from the energy-related aspect of training and can focus more on recovering from muscular stress. This means that you will enter into an anabolic state quicker and more recovery can be done per muscle per day. Less resources (nutrients and energy) spent on energy, more resources (nutrients and energy) spent on muscle!
Because you will also require less rest in between sets, your workout can either be shorter or include more exercises. Having higher energy levels also means that you will push harder during your weight training.
Skipping increases your metabolism, so your body will burn carbs quicker for energy. This means that you will need to make sure that you are eating enough carbs, otherwise your body will break down muscle. The brighter side of an increased metabolism is that your body is better able at producing energy, which can also be used for muscle growth and recovery.
Better Immune System
Being more physically fit increases your immunity so that you get sick less often, we all know how illness can set us back a few weeks!
Skipping Tones Your Body
Skipping is a great way to keep your bulk phase as clean as possible (more muscle, less fat) and speed up cutting phase (shorter duration needed, better results at the end)
Skipping Tones Muscle
Skipping tones the shoulder, arm, ab, quad, hamstring and calve muscles. Adding an aerobic exercise like skipping to a weight training exercise will add a separate stimulus to the calves, for example, challenging them to grow bigger to adapt.
Good Joint Health
High rep training helps to solidify joints so that they are stronger during low rep training. Skipping helps to build shoulder joint stability, for example, so that they are less prone to injury under the bar.
Add Jump Rope To Your Routine, But Don't Subtract It!Let skipping add to your workout, but don't let it take away from your original goal. As great as skipping can be as a complimentary exercise to a muscle growth program, too much can be a bad thing. If your main objective is to grow muscle, do not skip so much before weight training that you don't have enough energy to finish you training at an optimal level. As well, skipping too much after a workout might overload your body so that it spends less of it time recovering (and growing) from muscle stimulus to cope with the stress of this intense cardio. One of my favorite ways to include skipping into my routine is to skip at night because I train in the mornings, so that it does not interfere with muscle growth. Additionally, don't push yourself too hard when skipping. Rather give 100% during weight training workouts and around 60% when you skip. Don't try to push yourself to perform better in the same way you push yourself to improve on every workout. Your body will slowly adapt with time and rather increase the intensity or time over smaller increments so that your body spends more of its precious resources on muscle growth instead of trying to adapt to skipping more.
