V-Taper Sprint: four weeks with width in the lead slot
Four weeks where the first thing you do is a vertical pull. Lat Width leads two sessions out of three, Upper Back takes the third, and your scan fills everything behind them.
What is V-Taper Sprint: four weeks with width in the lead slot?
V-Taper Sprint is a four-week BackMaxx focus block that leads two of its three sessions with Lat Width and the third with Upper Back. Each lead session opens with the heaviest vertical pull your kit allows and closes on a lat-length stretch. Your weekly scan still fills the slots behind the lead.

Who should run V-Taper Sprint, and who should not
Run it when Lat Width came back lowest on two scans in a row and you can already take a vertical pull through a full range. A pulldown you control from a dead stretch counts. A strict pull-up counts. The block spends its best sets on that one pattern, so the pattern has to be loadable before the four weeks start.
Do not run it if the pull-up is still the thing you are working toward. Leading with a movement you can only half-complete hands the lats a short range and your arms the rest of the rep, and Pull-Up Progression exists for that gap. It runs six weeks instead of four and treats the bar as the goal rather than the tool.
There is a second reason to walk away. Not one of the 21 Lat Width movements in the corpus tags the Erectors, so if Lower Back is your lowest zone, four weeks of lat-led sessions leave that column of muscle to whatever the scan drops into slot three. Sort out the order of your priorities before you commit the lead slot.
What the week looks like
The block defines three sessions and rotates them across however many days you train. Lat Width leads the first two. Upper Back leads the third, which is where thickness work is parked so it keeps ticking over while width takes the attention.
| Session | Leads with | Opens with | Second slot | Cool-down leans on |
|---|---|---|---|---|
| A | Lat Width | The heaviest vertical pull your kit allows | A second lat angle | A lat-length stretch |
| B | Lat Width | A different grip on the same pattern | A second lat angle | A lat-length stretch |
| C | Upper Back | A row, blades before load | A second row angle | Mid-back and torso |
How often you train changes what you actually see of that. Three sessions a week gives you the full rotation. Two sessions a week means both of them lead with Lat Width and Session C never comes up, so you get width every time and no thickness lead for a month. One session a week reduces the block to Lat Width and nothing else, which is not what four weeks were meant to buy.
How the lat volume actually arrives
Through slots, not through extra sets. Every session hands its lead zone the first two positions in the main block: the heaviest compound goes first, while your form is still honest, then a second angle on the same zone so the stimulus is not one-dimensional.
On a Lat Width session that second position is the one that earns the block its name. The opener is a pulldown or a pull-up, and both bend the elbow, which means the arm takes a share. Put the Straight-Arm Pulldown behind it at three sets of 12 to 15 — elbow locked, shoulder doing the whole job through extension — and the lats get an exposure the biceps cannot absorb.
Session length decides how much room is left behind those two. A 45-minute session carries six main movements. Thirty carries four. Fifteen carries three and no cool-down at all, which means the lat-length stretch the block is built around only shows up if you give the session half an hour.
What changes by the end of week four
Width gets read at one place: the line from the armpit down to the waist. The Lats set how long that line is. The Teres Major sets how abruptly it starts, which is why the small bulge under the armpit does more for the V than another inch of mid-back would.
Four weeks of two lat-led sessions is enough for that upper corner to stop looking like a straight drop off the shoulder. Expect the change to show at the top of the taper first and further down last.
It is not enough to change your waist, and a taper is a ratio of two measurements. Half of the thing you are chasing is not trained by this block at all.
How to tell it worked
Re-scan at the end of each week, not at the end of the block. Four weekly scores tell you whether the line is moving; one score at the end tells you only where you finished.
Lat Width is the zone most sensitive to how you stand for the photo. Arms hanging in slightly different places read as different widths, so pick one arm position and keep it for all four scans. Same spot, same light, same distance from the camera.
Two numbers move at different speeds here. The zone score answers to the block within a few weeks. The shoulder-to-waist ratio barely moves in four, because your waist is doing half the arithmetic and no vertical pull touches it.
What to run after V-Taper Sprint
Scan before you decide. The zone that comes back lowest after four weeks of lat work is usually not the one you would name from memory.
Width with nothing behind it reads flat from the side, which is the failure this block sets up. If Upper Back is now your lowest zone, Thickness Block takes the same three-session structure and puts rows in front, so the back you widened gains some depth to go with it.
If Lat Width is still lowest, hand the plan back to the scan for a stretch of ordinary weeks before you run the block again, and change the opener when you do. The pool has 21 movements in it — six on the bar, six bodyweight, four on the cable — so a second run has no excuse for repeating the first.

Frequently asked questions
How long is the V-Taper Sprint program?
Four weeks. It defines three sessions, and the lead zone rotates across them: Lat Width, Lat Width, Upper Back. The rotation follows the number of days you train, so at three sessions a week you see all three, and at two you only ever see the pair that lead with Lat Width.
Does V-Taper Sprint add extra lat volume?
It adds slots rather than sets. Lat Width takes the first two positions of every lead session, so the heaviest vertical pull goes in while you are fresh and a second lat angle follows it. The zones that would normally have taken those positions move down the session instead of disappearing.
Can you run V-Taper Sprint at home?
Yes, if you have something to hang from or a band. Thirteen of the 21 Lat Width movements are available in a home session, including six on a pull-up bar plus the Banded Lat Pulldown and Banded Straight-Arm Pulldown. Without a bar or a band, the lead slot has nothing vertical to fill it with.
Will my Lat Width score go up in four weeks?
Often, but the scan reads the outline of your back rather than the work you did, so a week of poor lighting can hide a real change. Scan weekly from the same spot with your arms in the same place, and judge the trend across four scores rather than the last one.
What should I run after V-Taper Sprint?
Re-scan first, then follow the number. Upper Back lowest points at Thickness Block. Lat Width still lowest and pull-ups still hard points at Pull-Up Progression. Nothing clearly lowest means the scan-driven week is the better use of the next month than a second block.
