Do I have to answer this myself ...........lol
If I could I would....

I like to do hack squats or leg press for this. I place my feet close together and high on the platform. Make sure you concentrate on pushing with your quads and not as much with your glutes.
For overall leg development squats will be the best. They will hit every aspect of your quads and glutes very well.

Easto I cannot do squats do to knee and ankle problems.Leg presses I started doin again ,high volume medium weight for a good pump.I,ve tried different foot placements on leg presses and found that high and feet closely positioned hits my hams as well .I,m now placing my feet at the center of the pad on leg presses one foot apart will this help as well for outer thigh sweep?
Thanks for the response ......

What you have to do is experiment. Use different foot placements until you find one that hits the quads the way you want them to. Let me know if you have any more questions Bro.

Thanks for the response bro.Their aint enough enough training info on this site .After 15 yrs of training I still have questions .
