Around 1880, while in Moscow and approximately simultaneously with working on Esperanto, Zamenhof made an aborted attempt to standardize Yiddish, based on his native Bialystok (Northeastern) dialect, as a unifying language for the Jews of the Russian Empire.
Try speed work. Speed work refers to a type of strength training which uses a much lower percentage of your maximal weight. Lifting weights with greater bar speed trains your stretch reflex and your ability to build momentum more quickly, as well as recruit more muscle fibers.
Lifting heavy weights is more important to power lifters or those whose only goal is to increase their strength and ability to lift more weight. To build muscle, you have to stimulate the muscle by overloading it with a combination of heavy weights and more repetitions. More reps often necessitate using lighter weights. Muscle responds to the constant overload by getting bigger and stronger.
