Theme: When the theme entries are vertical, it generally means there is some sort of a gimmick. The presence of circles in the grid confirms this notion. If you didn't get them, then this theme would be very opaque. The circled letters, when read in reverse, spell part a certain kind of fitness activity. The vertical orientation suggests that the implied common word is UP.
3 D. "It's safe to come out": THE COAST IS CLEAR. Idiomatic, suggesting that there are no enemies in sight. The contained word, when read up is SIT, giving us the SIT UP -- an abdominal endurance training exercise to strengthen, tighten and tone the abdominal muscles. Our multi-talented oldest granddaughter, Amanda, is a certified fitness trainer, and she assures me that this is a completely useless activity.
9 D. Predictors of most 20th-century U.S. presidential elections: GALLUP POLLS. Gallop is an organization that conducts polls: assessments of public opinion by the questioning of a [presumably] statistically representative sample. Here the contained word is PULL. A PULL UP is a closed-chain movement where the body is suspended by the hands and pulls up. As this happens, the elbows flex and the shoulders adduct and extend to bring the elbows to the torso. Resistance is provided by body weight.
25 D. User's rescuer: TECH SUPPORT. This is a service provided by a hardware or software company which provides registered users with help and advice about their products. The contained word is PUSH. The PUSH UP is an exercise in which a person lies facing the floor and, keeping their back straight, raises their body by pressing down on their hands.
11 D. Workout suggested by the circled letters and their orientation: EXERCISE ROUTINE. This is what you get when you combine these items. My routine involves a tread mill and free weights, instead.
