For one week straight, I sipped coffee about 15 minutes before my early-morning workout. Here are the workouts I did and the amount of coffee I drank.
Sunday (9 a.m.): hot yoga; 3 oz. store-bought cold brew (about 60 mg caffeine)
Monday (5:45 a.m.): CrossFit; 4 oz. store-bought cold brew (about 70 mg caffeine)
Tuesday (6:30 a.m.): Kayla Itsines's BBG at home; 4 oz. store-bought cold brew (about 70 mg caffeine)
Wednesday (5:45 a.m.): CrossFit; 5 oz. store-bought cold brew (about 80 mg caffeine)
Thursday: rest
Friday (5:45 a.m.): CrossFit; 6 oz. strong-ass coffee my husband made (must have been like 120 mg of caffeine or more!)
Saturday (8:30 a.m.): hot yoga; 4 oz. watered-down strong-ass coffee (about 70 mg caffeine)
