Exercise is all about biomechanics. It's about understanding the force, resistance, and axis of the levers in your body and using them to your best mechanical advantage; this means making your exercises as efficient as possible. You can't just change where your elbow bends to make bicep curls easier. You can however change your environment.
Now, I'm not sure how you can modify a bicep curl other than changing the weight but, here are ways to modify push ups. Last August I wrote about Three Ways to Push Up, presenting two more...The first I would call Intermediate-Advanced.
1. Find a bench. Plant your hands on the edge the bench, fingers pointing away from you.
2. Walk your feet out so that your body is flat like a plank.
3. Push up as you normally would.
Try the second one if you are comfortable with your standard push up.
1. Find a step or low bench. Plant your toes on the top of the bench.
2. Walk your hands out to where they normally are for a push up.
3. Push up as you normally would.
In health,
