The second measured Balance day, and every number in Part I has climbed. Twelve back leg raises, lifting one straight leg behind you while the standing leg holds you up, 6 jumping lunges, and 12 side leg raises; counts are totals, so 6 per leg on both raises. Run the three in order, rest 2 minutes, repeat for 3, 4 or 5 sets. Part II and Part III then return unchanged: 60 seconds on one leg with the eyes closed and the arms out, followed by the timed hold with both arms out to the sides, palms down, kept up until they will not stay there.
Keeping Parts II and III identical while Part I grows is deliberate. A measurement only tells you something when the conditions stay the same, so the minute and the timer have not moved since Day 8 while everything around them has. Part I meanwhile has traded balance lunges for back leg raises, which take the same standing leg and load it with less movement and more time - the hip extends behind you slowly while the rest of you stays put. The jumping lunges went 4 to 6, the only explosive movement in the session and the only one that leaves the ground.
In back leg raises, lift the leg with the glute and stop before the lower back arches; the torso stays upright rather than tipping forward to buy height. Side leg raises stay slow with the toes pointing forward. Land the jumping lunges softly and switch legs cleanly in the air. In the timed hold, keep the palms turned down and the arms level, because the test ends when they sink and not when they ache.
Same minute, same timer, eight days of work in between. The difference is the reading.
Make it Harder: Take the back leg raises at a 3-count up and a 3-count down and keep the sets as written.
Make it Easier: Walk through the lunges instead of jumping them, and shorten the range on the leg raises.
