One hand on the saddle , the other on the lever, I stood panting heavily in attitude to mount again.

我一手抓鞍座，一手抓杠杆，气喘吁吁地摆好了再次登上机器的架势。

There is proper leg extension between the saddle and the pedals. Do this by having a friend steady your bike, or mount your bike in a stationary trainer with the wheels level.
