Abstract: Bridges and bird-dog exercises are commonly used in general training, as well as in warm-up and cool-down routines for young athletes to boost performance and prevent injuries. They are frequently paired with limb and other trunk exercises, and performed without precise control over intensity, which hinders the understanding of their actual impact. This double-blinded randomized controlled trial aimed to evaluate the effects of two bridging and bird-dog exercise programs (one emphasizing intensity, the other volume) on trunk performance and whole-body balance. Sixty participants were randomly assigned to a control group and two experimental groups, both of which performed bridging and bird-dog exercises at a specific intensity controlled by a smartphone-accelerometer. The exercises were conducted twice a week for six weeks at the university sports complex. The effects were assessed on: (i) trunk stability, through the bridging and the bird-dog lumbopelvic postural control, the unstable sitting and the sudden loading sitting tests, (ii) trunk endurance, through the front and the dominant side bridge endurance, and the Biering-Sorensen tests, and (iii) whole-body dynamic balance, through the Y-Balance, the tandem and single-leg stance, and the single-leg triple hop tests. Pre-post changes were reported in both absolute (Δ) and relative (Δ%) values. A two-way mixed ANOVA assessed differences between experimental and control groups, while paired t-tests analyzed within-group pre-post changes with a significance level set at p
