Here's a "conditioning tour," for a day when you need exercise, you need some time outdoors, but you don't have a partner, and/or don't want to rope up:
Start on the East Side:
1. Hike up Bear Gulch to the reservoir. After reaching the dam, turn to the right and climb the class four route on the back side of Tiburcio's X;
2. Descend and move to the dam and then up the Chalone Peak Trail. Take this a short distance to The Sisters, move up to their north side and ascend Second Sister by way of one of the class four Northwest Chimney routes;
3. Descend back to the Chalone Peak Trail, continue a very short distance to the climber trail that leads to The Hand and The Frog. Go partway out this before moving left up the climber trail to Gertie's Pinnacle. Climb the class four North Side Chimney on this formation;
4. Return to the trail that leads to The Frog, hike to that formation and climb the class two South Side Shuffle;
5. Descend back to the creek that leads into the reservoir, but do not turn right to return. Instead, hike up toward Knuckle Ridge, continuing to Little Flatiron and ascend that (class four);
6. From Little Flatiron continue up the ridge toward Scout Peak. Continue past this formation to Possibility Pinnacle and a superb class three to a great summit;
7. Continue to the High Peaks Trail and then hike north on that to Spike's Peak. Climb Kermit (class four);
8. Return to the High Peaks Trail, move just a little further north and then leave to trail to ascend Frothy Flake (class four);
9. Return to the trail and move to Dragonfly Dome. Descend between this and Sidehorse to Egg Shell. Continue downhill on the west side of Egg Shell, cross country to The Citadel (with care and some study, this cross country route can be done with very little brush - I've done it three times). Climb the class four route on The Citadel's south side;
10. Descend and then move around to the north side of The Citadel. Take the climber's trail toward the West Side, but divert up and left to class four Penny Pinnacle;
11. Return to the climber's trail and take this to the Balconies Trail. Take this trail past The Flumes and almost to The Balconies before taking the climber's trail to Crowley Towers. Climb the class three Tower Two;
12. Move over to the class two Tower Five;
13. Descend back to the Balconies Trail. Take this to Smiling Simian. Climb the 5.0 Easy Route on this (the only class five on this tour).
Return to the Balconies Trail and take this to the Chalone Creek Trail which can be followed to the Chalone Creek maintenance area on the East Side. Continue back to the east side parking areas.
