What’s the difference between free weights and using X3 system with variable resistance?
Free weights such as dumbbells and barbells give constant resistance. For example, if you do a bicep curl with 25 pound dumbbells, the resistance is 25 pounds when you start the exercise and 25 pounds when you finish the exercise. It is constant. It does not vary.
The X3 workout system uses variable resistance, which effectively lowers the resistance during the weightlifter’s weakest range of the lift and increases the resistance during the stronger portion. As a result, you put less stress on your joints where you are weaker and more stress at points in the range of motion where you are strongest. You will maximize the force being applied to the muscle, which builds greater muscular activity.
Here are 7 different studies that show how variable resistance is superior to weight training with regular weight. The factor that makes the difference is VARIANCE. X3 provides the strongest level of variance ever seen in a fitness product hence more growth over other programs:
(Ghigiarelli, et al, 2009). 7-week heavy elastic band upper-body power in a sample of division 1-AA football players.
(Joy, et al, 2016). Performance is increased when variable resistance is added to a standard strength program.
(Rivière, et al, 2017). Variable Resistance Training Promotes Greater Strength and Power Adaptations Than Traditional Resistance Training
(Anderson, et al, 2008). Nearly three times greater for average power in some movements was observed comparing control group to test group for variable resistance versus standard weight training.
(McCurdy, et al, 2009). variable resistance banded bench press produce similar short-term strength improvement conventional free weight bench press while minimizing shoulder stress.
(Godwin, et al, 2018). Pushing power increased over standard weight protocols using variable resistance exercise.
(Cronin, et al, 2003). 10 weeks analysis showed banded resistance training resulted in a 21.5% performance increase compared with the control group.
