So once you're not constrained by that 150 minutes per week and and honestly that's my hope. My hope is that everybody listening to us right now even though once in a while they might be constrained by that but that they can find more time to exercise. um the limiting factors start to become fatigue and recoverability uh and even to some extent adherence and I think that that's especially as you get older fatigue and recoverability become real limiting factors.
