The exercises that allow you to use the greatest amount of weight are the ones that help you build muscle the fastest. These also happen to be the lifts that allow for the greatest percentage of increases in loading. We’re talking compound (multi-joint) exercises here, done with free weights. You’re not going to grow at nearly the same rate with a workout comprising machine exercises and isolation movements.

Running with a sway to one side or experiencing muscle spasms? If your gait is off, it could be a sign of weak glutes. “A stiff hip joint would usually cause a more severe or obvious altered gait. If there is hip stiffness/poor mobility in the hip joint, it will lead to abnormal movement in all of the hip stabilizer muscles, including the glutes, and eventually pain and weakness,” Bayes explains.

Note that this recommendation is for total weekly volume, which means it would need to be divided up based on how many times you’re training each muscle group per week. So, for example, someone training everything twice per week would do 30-70 reps for each bigger muscle group in each of those workouts, and 15-35 reps for each smaller muscle group in each of those workouts.
