This complementary session deliberately changed the position before returning to the straight-arm plank. After five minutes of stretching, I completed four three-minute forearm planks with one-minute recoveries, followed by one six-minute straight-arm hold.

The forearm work

All four forearm-plank sets felt easy and controlled. After months focused primarily on straight arms, the position did not create meaningful difficulty during these short blocks.

The four sets contributed twelve minutes of specific isometric work without repeating the exact stress of the test position.

The final six minutes

After one further minute of recovery, I moved into the straight-arm plank. These six minutes felt clearly more demanding, and I checked the watch around the halfway point.

The contrast between the two positions was useful: total time alone did not describe the load. The final hold carried the fatigue and specificity that the forearm sets did not.

Residual fatigue

My shoulders and the area where the biceps meets the shoulder still felt sore, probably as a consequence of the twelve-minute continuous hold on July 3. I completed the session, but the earlier workload had clearly not disappeared.

The next sessions must distinguish normal muscular soreness from increasing joint or tendon pain. Completion is not evidence that every signal should be ignored.

Numbness beyond the plank

The fingers had also become numb while driving and cycling. That observation suggests the symptom may not depend exclusively on the plank position and may involve prolonged pressure, wrist position or irritation elsewhere along the arm.

Because several causes are possible, the useful action is not to guess. I will continue recording when it appears and seek professional assessment if it becomes more frequent, occurs at rest, persists or is accompanied by weakness.

THE TAKEAWAYComplementary work can reduce one kind of stress while still revealing what the body has not yet recovered from.
