Finding Sensory Input in a Healthy Way

It took me until I was 30 years old to realize that my self-harm I started when I was 10 was less for emotional release but more a desire for significant sensory input. I've developed more socially acceptable ways to receive the sensory input (like sport climbing/bouldering) but I'm failing to find other ways to meet my needs when I can't get to the gym. I use chewies and weighted blankets/vests, but it's sometimes not enough and I get worn out much faster than I would if I could spend 5 minutes putting all my effort into utilizing every muscle I have. Really looking for something that could be done in an office setting...
