Doing a special kind of workout called 'lacto-resistance training' for four weeks helped pro bodybuilders get stronger in leg exercises—maybe even a bit more than regular training—even though they hadn’t been responding well to workouts before.

What we've found so far does not support the idea that lacto-resistance training improves squat and leg press strength more than traditional training in professional bodybuilders. In fact, the evidence we've reviewed leans against it. Our analysis of the available research shows that out of one assertion examined, zero studies support the claim that lacto-resistance training leads to greater strength gains in squat and leg press compared to traditional training [1]. Instead, we found 52.0 assertions that refute this claim [1]. This means the current body of evidence we’ve analyzed does not align with the idea that this type of training offers a strength advantage for professional bodybuilders, even in cases where individuals may have plateaued with regular training. We want to be clear: this doesn’t mean the idea is impossible or that future evidence couldn’t shift our understanding. But based on what we’ve reviewed so far, the data does not point toward lacto-resistance training being more effective for building lower-body strength in this group. There are no supporting studies in our current dataset, so we can’t say there’s any measurable benefit shown at this time. We also don’t have details on what “lacto-resistance training” involves, how it was applied, or how strength was measured—our analysis is limited to the numerical weight of the assertions provided. As always, our analysis is ongoing. New data could change how we interpret these findings. Practical takeaway: Right now, there’s no evidence we’ve seen that this special workout method helps pro bodybuilders gain more strength in leg press or squat than regular training. If you're considering trying something new, stick with what’s been shown to work—unless future evidence gives us a stronger reason to rethink it.
