What is the springload and reps for Back Extension #5 Thoracic Extension?

• A. 1-2 springs; 12-15 reps
• B. 0.5-1.5 springs; 8-10 reps
• C. 2-3 springs; 6-8 reps
• D. 0 springs; 4-6 reps

Answer: (B)

Back Extension #5 Thoracic Extension is about using just enough resistance to move through the thoracic spine with control while keeping the pelvis stable. The best prescription is a light spring load—roughly 0.5 to 1.5 springs—and about eight to ten repetitions. This combination lets you lengthen and extend through the thoracic region without forcing the lower back into excessive strain, promoting endurance in the upper spine muscles and maintaining good alignment. Using more resistance (two to three springs) can restrict range of motion and make it harder to maintain form. Using no resistance (zero springs) won’t provide enough stimulus for strengthening and motor control. Four to six reps would under-train the endurance aspect, while twelve to fifteen reps could lead to fatigue that compromises technique.
