One of the bullpens at my new job pitched in and got a pull-up stand! It brings people to visit and makes the place feel like we own it a little. That's a good selling point that it causes you to rotate your shoulder blades back and up. Hanging leg lifts can also be done and are also a much more effective ab exercise than situps (since it only takes 10 reps to get tired, and you can bring your knees closer or farther away to adjust the resistance).

We had one, until a bean counter had it removed over liability risk.

I'm a little confused by this brief post. Are they suggesting somehow incorporating the pull-up bar into your workstation setup or just installing one nearby and doing pull-ups periodically during breaks?

I think you're overthinking it; I just meant, "do a few pullups every now and then, and you'll feel better."
