Active recovery days can be great for beginners. You’ll be moving your body and giving yourself something to put in your workout log without overtaxing your body. It also helps you set good habits for later, when you are training more intensely.
That said, if you’re a beginner, you might want to avoid the conditioning component of active recovery days. It may be counterproductive if your active recovery day starts to feel exactly as active and challenging as your regular training days. Stick to mobility work and steady state cardio until you’ve built up more work capacity.
