You don't "lift" the bike up onto the stand. If you do, you will always have difficulties and possibly ruin your back.
You roll the bike backwards onto the stand.
1. Press stand down to ground.
2. Move left foot to press down on the stand's foot - NOT the tang.
3. With left hand on handlebars and right hand on the grab handle - with a slight upwards tug you roll the bike backwards and up onto the stand.
Some people actually will start the process about a foot ahead of where they want the bike to sit, just so they can get a slight rolling start.
It seems simple, and most people have problems putting the concept into practice. But once you get it to work properly for you, it really isn't all that hard, unless the stand is knackered.
