Many of you have probably heard of Dr Mike Isretil of Renaissance Periodization , and he has popularized a concept over the years called the stimulus to fatigue ratio . You might even call it a principle that has held up pretty well when you look at the evidence and practical application , and it could be a game changer in how you approach your workout and how you think critically and intelligently about your programming . What is the stimulus to fatigue ratio ? It's very simple it's a way to measure the effectiveness of a strength training exercise by comparing the amount of muscle growth stimulus or stress that it provides to the amount of fatigue it generates Simple stimulus to fatigue . The goal , of course , is to maximize muscle growth while minimizing unnecessary fatigue . This is important because if you're constantly exhausted from your workouts or you're easily building up fatigue for many of us that would be , for example , in the low back or potentially in the shoulders and the neck area and you're not seeing proportional gains despite all of that , slamming your body like that day after day , session after session , you might have too much high fatigue , low stimulus exercise , or even if it is high stimulus , it still has a high fatigue as well , which makes it harder to recover . The key with this concept is finding exercises that give you the best balance for your recovery abilities , that offer the most stimulus and growth with the least wear and tear on your body .

The classic example , of course , is the deadlift . The deadlift is fantastic . It is one of , if not the best exercises out there , competing right there with the squat when it comes to overall strength and muscle size , but it generates a lot of fatigue . Even if you do everything right , it can be a killer on your low back . It might not be the best choice . If you're aiming for higher frequency , higher volume , working out the legs several times a week , developing your hamstrings , even developing your back , you might find that you need to mix in other pull movements or Romanian deadlifts instead of full-up deadlifts , or even other exercises like I don't know leg presses and other movements . Maybe that's a bad example If you're trying to work the hamstring , it might be good mornings , it might be leg curls , things like that .

To give you a little bit less fatigue but still get an overall good amount of stimulus Makes sense . So applying the concept of stimulus to fatigue means evaluating your exercises and your programming with a critical eye . You ask questions like is this movement giving me the stimulus I need ? How taxing is it on my body , and can I recover adequately before my next workout ? It's training smarter , not just harder , and for those of us that are now in our 40s or older , that's the key to sticking with this for the long term and being consistent is balancing the stimulus and fatigue . Train efficiently , grow stronger and avoid burnout .

All right , that's it for today's quick wits . Think about this stimulus-to-ease ratio as you plan your workouts . It's not just about lifting heavy , it's about lifting the right way for the long game . Thank you for tuning in to another episode of Wits and Weights .
