Complete 50 climbups in the least amount of sets possible, within 1 hour.
-You can use a rail if you need to but ideally use a flat wall with no overgrip.
-Rest a maximum of 3 minutes between sets and do as many reps as you can each time.
-If you complete it in 5 sets or less then you've done very well, but finishing it at all is an achievement!
-You have a 1 hour time limit so if you don't quite make 50 then just do as many as you can within the time limit and try to beat it next time.
-Good luck and remember to stretch afterwards.
