騎腳踏車是一種絕佳的有氧健身運動。在室內踩健身腳踏車或騎腳踏車到室外去欣賞一下風景。慢慢地開始你每天例行的運動,先花五到十分鐘的時間來暖身,讓你的心臟進入適合運動的狀態(tài)。接下來加速騎十到二十分鐘,最后再慢下來騎五到十分鐘。
Most stationary bikes help you clock your pace.Set the bike to an easy resistance level and pedal about 40 rpms(revolutions per minute)to start.Then increase your pace to 60 rpms and hold it steady for about 20 minutes.Finally,slow down to 40 rpms or less for about five minutes.Afterward,walk around the room for a few minutes to let your heart re-adjust to a non-exercise pace.And don't jump into the shower right away-that could seriously stress your heart.
大部分的室內腳踏車可以計算你踩踏的速度,一開始先把腳踏車速度等級設定在較容易的每分鐘四十轉,然后逐漸增加到每分鐘六十轉,并以此速度持續(xù)踩二十分鐘。最后,將速度降到每分鐘四十轉或少于四十轉,持續(xù)約五分鐘。之后,在室內走一走,讓你的心跳重新調整回非運動時的頻率。不要急著去沖澡,那可能會嚴重地增加你心臟的負荷。
