I love your books and have been making great gains on your program. I have two questions if you don't mind answering:
1) I do not have a Prowler currently, one day I will have me one of them, and no hills in my vicinity. But right now I do have a nice sized tractor tire. Can I substitute tire flipping for wherever you have Prowler or Hill Sprints work in your routines until I get a Prowler? I was thinking 10 flips for 5 to 10 sets would be a killer Prowler or Hill Sprint substitute.
2) I am 44 years old, and doing Squats with a barbell and even a Buffalo bar kill my shoulders. Can I substitute Safety Bar Squat bar and/or Dave Drapers Top Squat apparatus for straight bar and Buffalo bar Squats as the main exercise??
Thank you so much Jim
