Assisted Standing Triceps Extension (with Towel)

Using a towel for an assisted standing triceps extension lets you use the non-working arm to help guide and support the working arm through the movement, which is a useful fix when a straight dumbbell extension feels unstable overhead. It isolates the triceps in a similar way to a standard extension but with more control. It's a good option when equipment is limited to just a towel and bodyweight.
