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.
For your lower body, warm up with squats. For your upper body, use a combination of bench presses and rows. Start with a weight that you figure you can lift 15 to 20 times, but perform only six repetitions. Wait 30 seconds, increase the weight to an amount you can lift just 10 to 15 times, and do four repetitions.
