The 30 Day Burpee Challenge аналитика приложений для 9 декабря

Burpees: we love to hate 'em, but if you stick to this 30-day challenge, you'll feel more stronger, tighter, and more toned by the end of the month. They’ve been called the most efficient exercise known to humankind, and doing them every single day is more rewarding than you could imagine. The burpee is an effective exercise that builds strength and challenges your cardiovascular system all at once. If that weren't enough, burpees also help you develop killer abs. The burpee requires no equipment and is an efficient, functional movement because it works every part of your body.
