1) Why do muscles grow after strength training?
Strength training can be defined as a certain number of muscle contractions against a force. These muscle contractions break proteins in your muscle. Your body repairs and replaces the damaged muscle fibers at an increased rate with a cellular process. Muscle fibers are fused together and form new muscle protein strands. The repaired muscle protein strands increase in number and thickness and create hypertrophy = muscle growth.
2) Eccentric and Concentric phase
Concentric = Shortening (when you bend your arm)
Eccentric = Lengthening (when you stretch your arm)
1 repetition in strength training consists of a concentric and an eccentric phase. Traditional gravity based training focus on the concentric phase, you focus in your current training primarily on the concentric phase when you bend your arm. With the Strexbox you can train now the eccentric phase efficiently.
3) Traditional weight problem number 1: Sticking point
Solution: STREXBOX constant force through the whole range of motion
Traditional weight training uses the gravity of weights or your body as resistance. Let us explain it on the exampe of the squat position. In the squat position you bend your legs and go down with your butt towards the floor, towards gravity. The direction of the gravity is always the same, but the force you need during the range of motion changes when you bend your knees. The highest force you need where weight has the slowest speed and longest distance from your active joint, in the squat position your active joints are your knees. The point with the highest force is your “sticking point”.
In the squat position your sticking point is your legs are bend and your butt is closest to the floor. At your 1 repetition maximum (1 RM) you just pass the sticking point, but you would be able to add much heavier weight at other points in the range of motion of the squat exercise. STREXBOX solves this problem, STREXBOX gives you a constant tension on your muscles through the whole range of motion! This means, you train your muscles with highest efficiency in any angle during the range of motion of your exercise. Additionally it is easier on the joints (better for your knees) and safer, because the highest load is not on your sticking point.
With a STREXBOX you will train with higher average force than compared with traditional weights or body weight which leads to more muscle growth and more muscle strength. Additionally to pass the sticking point with traditional weights or body weight nearly every athlete cheats, meaning you slightly change the angle or the speed of the motion, which is of course not optimal for your training success. With STREXBOX you cannot cheat, maximum force in every angle through the whole range of motion for maximum training success.
4) Traditional weight problem number 2: maximal set
Solution: STREXBOX maximal drop set
With traditional weights or body weight your last repetition before failure is maximal if you continue until failure. But could you do 3 more repetitions with let´s say 80% of your body weight? Probably yes. But you cannot lower your body weight during the squat or alternatively change the additional weight plates which creates a break and makes it impossible to gradually lower the force after you have reached your last repetition before failure with traditional weights or body weight.
With STREXBOX your maximal set is really the maximal drop set. With STREXBOX you can continue after you would have reached your last repetition before failure on traditional weights with let´s say 80% or whatever you still have left inside of you until you finally drop 🙂
5) Traditional weight problem number 3: insufficient eccentric load
Solution: STREXBOX eccentric overload
With traditional weights or body weight you mainly train the concentric phase (stretching your legs). You hardly can train the eccentric phase (bending your legs) efficiently.
a) The eccentric phase cause more muscle damage, which means your body repairs your muscle at a higher rate which lead to more muscle growth. To optimize your training results, you need more focus on the eccentric phase.
b) Your muscles are stronger in the eccentric phase than the concentric phase. This means your 1 repetition maximum (1 RM) is higher in the eccentric phase than the concentric phase. This means you are not training 100% of your 1 repetition maximum (1 RM) in the eccentric phase right now and loose training success. To optimize your training results a training which has less weight on the concentric phase (1 RM of your concentric phase) and more weight on the eccentric phase (1 RM of your eccentric phase which is greater than 1 RM of your concentric phase) would be optimal. This is called “eccentric overload”. This can be easily achieved with the STREXBOX.
