What is the optimal repetition range?

The optimal repetition range can vary significantly depending on specific training goals such as increasing strength, building muscle (hypertrophy), or enhancing muscle endurance.

1. Strength Focus:

   • For pure strength gains, lower repetition ranges are generally recommended, typically between 1 to 5 repetitions per set. Working in this range with higher weights (around 85% to 95% of one-rep max) is optimal for strength without significant hypertrophy 1.

2. Building Muscle (Hypertrophy):

   • For hypertrophy, a slightly higher range is advised, from 8 to 15 repetitions per set. This range helps in maximizing muscle growth through extended tension and increased blood flow to the muscle 2.

3. Endurance and High Volume:

   • For muscular endurance and conditioning, high repetition sets (around 15 to 30 repetitions) can be beneficial. Such high rep sets are especially useful when they're performed at a lower percentage of one-rep max (like 30% to 50%) 3.

To practically apply these ranges, the key seems to be varying one’s training focus based on these rep ranges and goals. Training close to muscle failure within these specified ranges can maximize the benefits of the workout session. Moreover, integrating variety—both in repetition counts and weight loads—can provide comprehensive strength and hypertrophy benefits while preventing training plateaus and reducing injury risk.
