Yep, that's probably wise. Another queue is if you're quivering too much you might need to form some of the core for that exercise first—or you're just done. Lat pull-downs are a great start as you can set the weight while the movement is pretty near the same. Main difference being, you'll need some resistance bands or the equipment to do that one instead of just a mounted bar. Edit: My big beef with Crossfit and like circuits are that they do similar things: They recommend great methods for exercise, strength building, cardio, etc. However, they often have next to zero form coaching and some of the things I've seen people doing with their bodies right beside coaches and trainers in programs like that ... they're just asking for injuries (either short term, or long term. How they teach rowing form is particularly bad). It's less the exercise, and more the parameters—form and knowing your limits are core. In a coach, they should be able to judge what you're ready to be doing.
