It’s not cheap, but this novel, wood-constructed trainer platform fits nearly all trainers and provides controlled motion in the side-to-side and front-to-back planes. Though it’s stiff enough not to feel wobbly and take away your attention from the workout, it still provides a staggering amount of pain relief for rides of any length. Though Saris touts the platform’s ability to provide an extra core stability workout (which it does), in terms of pain relief, there’s not much else available that works as well. The only downside (aside from the price tag) is the very heavy, very tough-to-move piece of equipment is not conducive to temporary trainer locations. You’ll only want this if you have a dedicated pain cave.
