Weights for runners

Ever since all my injuries and surgeries, I've been putting a greater focus on strength, even though I may not always have time for extended gym workouts. One of my favorite half-hour workouts is below. It's adapted from this article, made to suit my own home gym equipment (which is just dumbbells).
The reps listed are on the lower end of an appropriate range, but that allows me to complete the whole workout in 30 minutes or less. I'm currently using my adjustable dumbbells with the 7.5-lb plates, so with the bar, probably 16 or 17 pounds each. If I want a harder workout, I add reps, or add a core workout at the end.

Posture:

1. Push ups on dumbbells. Three sets of ten.
2. One-legged bridges: 25 per side
3. Russian twists with weights, 3x10, sitting on cushion to add challenge.

Stability:

1. Clams x 50 per side
2. Hip side plank dips, 3x10 each side
3. Side leg lifts, 20 per side
4. Side bridge: Put one foot up on shelf, step, or stable chair; lift other leg up until feet touch and lower back down to ground. 10 x 3 per side

Strength:

1. Romanian deadlift, weighted, 3x8 reps per side
2. Deadlift, weighted, 3x 8 reps
3. Dumbbell on shoulders squats, 3x10 sets
4. Bicep curls 3 x 8 reps

Power:

1. Step or box jumps, 3x10
2. Jump squats, 3x 5-10
3. Four-square jumps. Set up imaginary square; jump from corner to corner (alternate directions; don't pause) x 10
4. Lateral jumps 3 x 6 reps (back and forth is one rep)
5. Kettlebell swing plus shoulder press x 10 per side
