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 weights increases muscle strength, muscle mass and bone density while also burning fat. Combining strength conditioning two to three times a week with a cardio routine will ensure a complete workout for your entire body. Beginning a weight training program can be scary if you've never done it before.
