Save for the bike, rather than thinking, "X amount of reps per round per movement" think, "40-45 seconds of work per station." If you establish a doable amount of work the first round, hopefully by the 5th round you will still be able to replicate that amount. Consistency will ultimately benefit you more than sporadic numbers. For the bike, you get to rest an entire minute afterwards, so there's no point in getting off early. If you've got a friend today, enjoy the company, and embrace the suffering. Welcome to 2019 Iron Grippers!!
