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.
Build up to about 15 repetitions with the lighter weights. Gradually increase your poundage over three to four weeks until you're lifting 10- to 15-lb. weights if you're a woman and 12- to 20-lb. weights if you're a men. The higher the weight, the fewer your reps, with a maximum of between eight and 12.
