strenuous
Requiring great effort
Strenuous describes activity requiring great effort or energy: a strenuous hike, strenuous exercise.
It applies to both physical exertion and vigorous mental or emotional effort: strenuous objections, a strenuous campaign.
The word implies sustained intensity rather than brief bursts—something strenuous taxes your endurance.
