i ask b/c i see time as a limiting factor.
balancing sport training, strength, and conditioning is a time burden. i just feel that if you're already putting plenty of time into conditioning and you aren't seeing the fat loss, then either you're at your good performance weight, or you need to take time from the others and specifically work at fat loss.
on the other hand, long ass LSD may improve your conditioning for the better, so maybe you'll get a performance boost anyways.
but if you just want to look good, put your time wherever it needs to go
