If you're doing a double leg press (especially in conjunction with a Valsalva maneuver) you can get an instant BP reading as high as 320/250. If that's your idle BP then you're not long for this world lol.
If your BP - measured in a specific and consistent set of conditions - is elevated vs baseline then you are at an increased risk for a set of medical conditions. Researchers could have picked any set of conditions to establish that baseline but I assume that idle is easier to standardize on than e.g. double leg press with 3 RIR. It's not which condition per se but rather that it's the condition researchers aligned on and studied.
The problem is that if the risk is established based on your deviation from the baseline, then you must be measured in the same conditions under which the baseline was established otherwise the results don't mean much if anything at all.
