5/3/1 Second Set Last

A heavier 5/3/1 supplemental variant: the standard four-week wave on the main lifts, followed by 5 sets of 5 reps at the SECOND (middle) working set weight of the day. Significantly more taxing than FSL and intended as a short-term anchor block, not a long-term template.

Intermediate lifters running 5/3/1 who have spent time on a lighter leader (FSL, 5's PRO) and want to push volume at a higher relative intensity for a short block. Not a starting point — come to SSL with an established 5/3/1 training max.

Same 5/3/1 wave as FSL on the main lift. After the top set, drop the bar to the middle working-set percentage of the day and run 5 sets of 5 — 75% Week 1, 80% Week 2, 85% Week 3. Week 4 is a straight deload with no SSL sets. Total volume is similar to FSL but done at a heavier weight.

Training max bumps each four-week cycle: +2.5 kg upper, +5 kg lower. Wendler recommends running SSL for only 2 cycles post-reset before rotating to a lighter leader template — the intensity-volume combination is not sustainable longer term. Two consecutive stalled cycles trigger a full reset to 90% TM and a switch to an FSL or 5's PRO leader before a subsequent SSL anchor.

SSL was published by Jim Wendler in *Beyond 5/3/1* and refined in *5/3/1 Forever*, framed as an "anchor" template — heavier, shorter duration, best used after a leader block has built work capacity. VALDA adapts the wave and back-off structure for use inside the app, but does not claim authorship of the method.
