|For your first drop-in:
- stand on the coping on one feet, the 2nd on the platform,
- bend your knees
- when your are ready to go, put your 2nd feet on the coping (knees always bent), put your upper body forward and you go down
For the first tries, stay focused on knee bent, upper body forward during the descent and till you reach the other curved side (try to even to keep your hands down)
In order to cope with the coping:
-try to land on one feet, then the other and roll on the plateform
-then you can try to combine coping/rolling/dropin, etc
As a next step on small ramps/curbs, you can try to put your 2 foot on the coping at the same time, stand, jump turn and dropin. For the first tries, very often you have too much speed and continue rolling on the platform, so bend your knees before you reach the coping, jump a bit, and land knees bent (a bit) on the coping, hands at the vertical of the coping.
Hope this helps!!! Then you can learn slides/grinds!!!!
Don't hesitate to take movies of your run and others, by analysing them you will see what are your errors (head, shoulders and hand placements are very important)
