Luca, it sounds like you might need to dial back the weight and/or the reps/sets on the indoor ME workouts and then gradually re-increase as you’re able. They are taxing in a different way than the outdoor one. It can take 48-72 hours to recover from an ME workout. To not be “curing a damage” every week, dial back to a level that is not destroying you and then build more slowly.
Does that help?
