My answer has more to do with schedule than merits, but personally I wouldn't get all dressed up for a 1x20 workout unless that was litterally all the time I had available. I'd much rather get in 1-1.5 hrs of work if I'm going to have to get dressed, fill the bottles, pump the tires, and shower afterwards.robkit said:
If I only had 30 minutes to workout, I'd probably put off the L4 work for another day and do an L6 or L7 set instead.
