While putting two workouts on back-to-back days increases the total impact they will have on your fitness, you still need to maximize recovery between the two sessions. If you can complete the first workout in the morning and the second workout in the afternoon or evening, you can get more than 24 hours of recovery between them. And if you’re trying to build in even more workload, don’t add a third day to one of these blocks, but rather slide the block to Thursday/Friday and incorporate one or both days of the weekend. If you do this, however, be sure to take easy or off days Monday to Wednesday preceding the block.
