Mass Effect 1-3
Bioware’s sci-fi trilogy may have you wondering, “how the hell can I exercise to this game?”, but it is indeed possible. Start with a huge part of the game, obviously: conversation. Every Paragon or Renegade dialogue choice you make, do 10 squats or push-ups, or both if you feel like it, and 5 if you pick the neutral dialogue option.
For battle, we get serious. When an ally is downed do 15 crunches, 20 more if they come back after the battle is over and 25 more if you use medigel to revive them. Whenever you die, do 12 leg raises; do 6 if you’re close to death but manage to stay alive at the last minute. 10 standing leg raises whenever you level up, and 5 crunches plus 5 standing leg raises whenever you use a power, for yourself or your allies. And in Mass Effect 1, when you die and forget how completely dicks the checkpoint system was in it, do a minute-long plank. Increase the number of each of these by 10 when you go increase the difficulty level in your next playthrough.
