I am doing Dave Tate's Six Week Bench Press Cure and i had a few questions.
1) When the program asks for dumbbell extensions does it matter what kind? I am currently doing these http://www.youtube.com/watch?v=loZgGqCZr1Q&feature=PlayList&p=85EA8F8B25F46FF6&index=2
2) What is the difference between dumbbell extension on floor and regular dumbbell extension? Other than obviously being on the floor.
3) I have no training partner and no boards. Is pin press an acceptable alternative for board press?
4) Unrelated but important. My squat and deadlift are suffering due to a lack of core strength. I am currently using bodycurls, abb wheels, and turkish getups to solve the problem. Are there any other things you would recommend to work on this?
Thanks in advance for your help
