Is it permissible to combine reciting remembrance (dhikr) and exercising after Fajr prayer until sunrise to attain the reward of a complete ‘Umrah?

There is no impediment to performing remembrances (dhikr) during exercise, as Allah Almighty says: "Those who remember Allah while standing or sitting or [lying] on their sides." However, the reward of Hajj and Umrah (definition) is conditional upon performing the Fajr prayer in congregation, remaining in the prayer area until the sun rises, and then performing two rak'ahs.
