To increase strength, one needs to lift heavy weights. This helps to release human growth hormone, hydrogen ions, inorganic phosphate and other chemicals which also promote fatigue. A bit of a bind here.
You want to gain strength AND increase endurance but by focusing on one, it weakens the other. What to do? Supplementing with beta alanine will both increase strength and endurance. This increases carnosine levels which is a key antioxidant which protects cells and buffers acids which cause fatigue.
As a person ages, natural body producing chemicals associated with strength and endurance start to decrease. So does performance.
Adding Beta Alanine will counter natural decreases and improve strength and endurance in a short period of time.
