3-2-1 weekly – 3x weights, 2x Pilates & 1x cardio

Has anyone tried this method? I’m 63 & in pretty good shape. I’ve mostly done 3 days cardio (treadmill or spin) and 2 days yoga. Weight has been stagnant for 2-3 years. I finally added weight lifting 2x week with weight gain BUT improvement in body fat. Really only want to lose 5-7lbs. Would like to hear others experiences. Thanks!
