Used the Buffalo bar with chains: went to 415 then started adding chains 2 at a time. I think it ended up being 6 sets of doubles ending at a top weight of 415 and 11 chains per side. I couldn't get the bar situated on my back (felt like it would slip off) so some of the sets flt a little off, but not heavy.
Wheelbarrow: 3 or 4 passes of about 75-100 yards with 300 lbs right over the handles.
Rev. Hyper: 1 set of 20 with 600.
Found out that the meet I am planning to do in May is the same week of all my exams for class. Looks like I am going to try to beg my teachers to let me take them early, or look for a new meet.
