Finding it now a problem to get up from my wheelchair... to transfer, stand, etc.... I am now working on this issue. I took note of what muscles are used or "what hurts". I also tend to pitch forward, so ensure there is a grab bar, cupboard, table, etc. in front. When I find any movement difficult, I repeat it 10 times.
Also, with the standing thing, I found moving to the shallow end of pool edge, allows me to simulate the "getting up" process. Hurts in all the right places. "Squatting" while hanging on to pool edge, repeat 10 times. Also found that "walking" while hanging on, in the shallow end is difficult. Experimenting with standing (upper body out of water, no hanging on).
May also be useful to get out of recliner, bed, off couch...
