These 4 exercises are great for strengthening your core. I do them at least 3x a week after my training run.
Do each one for the prescribed number of reps or hold count:
1. Plank with Side Step x 10 reps on each leg.
2. Runner’s Crunch x 10 reps on each side.
3. Seated Twists x 15 reps on each side.
4. Swimming x 30 seconds.
Repeat entire sequence 2-3x if you have more time.
