The black-capped chickadee (Poecile atricapillus) is a small, nonmigratory, North American songbird that lives in deciduous and mixed forests. It is a passerine bird in the tit family Paridae. It is the state bird of both Maine and Massachusetts in the United States, and the provincial bird of New Brunswick in Canada.
Machines that work out and build your butt muscles include the leg press machine, smith machine and hip extension. Traditionally, the squat has been the most common exercise for building the muscles in the lower body.
For example: Crunches only work the front of your abs and donât create a very strong contraction, since it's just your own body weight youâre working against. The ab crunch machine that you sit in at the gym mostly just makes your hip flexor (or your sitting muscles) work hard and not your stomach.
