Perform the following:
3x10 Weighted SLS
3x5 NLC
3x6 Circular Arch-ups
3x60m Backward Sled Sprint
Finish with 60 seconds total aggregate work of a straddle L variation.
notes:
1) This workout should be performed as a modified giant set. To this end perform the Weighted SLS (alternate legs on each rep for a total of 5 reps on each leg) then rest 60 sec, perform the NLC then rest 60 sec, perform 6 Circular Arch-ups then rest 60 sec (alternate direction here for each rep), finally perform the sled/tire sprints and then rest 5 minutes before beginning the next modified giant set.
2) Add as much weight as possible to both the SLS and Circular Arch-ups. Do not be afraid to challenge yourself here; holding a 45lb plate during the SLS is not unreasonable for stronger athletes.
3) Be meticulous in using ONLY just enough assistance from the arms to complete each rep of the NLC.
4) Add sufficient weight to the sled/tire sprints to make the sprints quite challenging; the running should be very strenuous. The Backward Sled Sprints are the primary focus of this GB WOD and should be approached very aggressively.
5) If you do not have access to a tire or sled for sprints, then possible sled/tire substitutions include: perform the sprints with a weight vest, drag a kettlebell on the ground behind you while sprinting, have a partner pulling backward on you during the sprint with a long strap. The best substitute, and possible even better than the sled sprints, is to run up a very steep hill with a weighted vest.
