What I meant by dynamic was just the resistive force. 2pl8 is always 2pl8 no matter where you are in the lift but Bowflex's main selling point was the varying degrees of resistance through the motion like elastic band training. The repetitive motion thing was saying that their selling point was a meme. To your point even with a bar and what i would call static load, you train the neuromuscular system regardless and honestly I would think more efficiently since grug lifted rocks not and those rocks weren't attached to a spring. But I'm a retard. That's why I'm here asking if time under tension is a meme. <|endoftext|>
