The problem I see with the Circle Arch Up: SL/PE6, when attempting it alone/ without workout partner, is that I'm forced to use approx 60-70% of my hamstrings, in order to initiate and complete the move, when the percentage of the working muscle group should be around 80-90% for obliques and lower back (from my perspective, but I could be wrong also).
I want to perform this exercise as strict as possible (and yesterday I didn't have a workout partner) and don't want my SL to lack behind due to absence of teammates during the summer... Any creative ideas on how to do the Circle Arch Up: SL/PE6 alone in a gymnastics gym?
(Please view the images for a understanding of my current solution on this move, where I basically lay face-down on the vault table, fix my feet under the trampoline (as shown by the black strap) and put the 10 kg weight onto my hamstrings for further assistance).
Have a fantastic day!
