To gain muscle and improve strength, should you lift fast or slow?

There is a ton of research on this topic of repetition velocity. But what is the consensus? Should you be focused on slow eccentric? Fast concentric? Some combination of both? The article under review for this week provides some excellent insight to both sides of the speed argument, and even dives into separating the repetition all together. This is probably the episode the has the most take away use-able messages that you can apply to your training today to start seeing improvements. As always, I appreciate any reviews or comments you have on this episode or any other you have listened to! Enjoy!
