More endurance = more volume = more work capacity and performance down the line. Burning out faster doesn't mean you had a better workout... And definitely doesn't mean you got a better growth stimulus.
This. More endurance, either more reps in a set or more sets at the end of the workout, leads to more growth and progress. Even if your endurance is increased, you don't have to workout until you have nothing left if you don't want to; at the end of the day, more endurance is a good thing. You don't have to capitalize on it to the max, but why you wouldn't want it is beyond me.
I have actually switched over to Chained Out. I am tired of the same old crap. I love it as a preworkout. If you ask me there aren't any really good preworkouts left on the market that have it all...
1g of Creatine (no matter what form)...not enough
Beta Alanine - hate this **** and useless IMHO (why would you want more endurance in a workout. I want to burn out FASTER!)
That's my two cents...
In my opinion, there are more quality pre-workouts on the market than ever. There are plenty of bad ones, but there are at least a few that pretty much have it all; ingredients for energy, focus, pumps, and endurance. We now have citrulline and nitrates, which are better for pumps and endurance than arginine, which pretty much every pre-workout used, we have open-label supplements, etc. I personally use HyperMax XT, and find it provides me with energy, pumps, and endurance. I'd say that's a good thing. I don't have to workout for 2+ hours every day, even if I feel like I could, but more endurance (or at least the ability/potential to do more) is a good thing.
