Just starting the stretch series. I'm doing the Strong Lifts 5x5 program 3x per week and doing the stretches on my non-lifting days. Really loving it. I can get through the middle split and front split series reasonably well considering I'm just starting, but the thoracic bridge series becomes really hard for me right after the hand stand wall presses. After that, every stall bar move is either something I fail at completely, or barely get 1/2 way towards a rep.
For example, on the bridge with feet elevated on the stall bar, it's enormously difficult for me, once I'm up, to hold the pose, and even harder to walk my feet up the bars to where I can straighten my knees. My shoulders and arms get completely fried. By the time I'm done with that one I'm useless for the remaining work.
Are there assistance exercises/equipment that help with this? I feel like I need some support under my thighs or knees to help with even a single rep of the stall bar work. Walking bridge is a non-starter and doesn't seem to have a support video explaining the fine details. Any ideas?
