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.
No Upper Limit. Always start weight training with weights that you can lift comfortably eight to 12 times, for a set. Build up until you can do two or three sets in each workout, then gradually increase the weight. Reduce the number of repetitions if necessary when you add weight. There is no absolute upper limit -- the goal is to tax your muscles, without strain.
