You can make 20s pretty heavy! Try doing hyperextensions while holding two 20s to replace deadlifts. Bulgarian split squats and goblet step ups to replace squats. Bench you can replace with decline pushups and dips. OHP you can replace with pike pushups, putting your legs up on a chair or something and progressing to a head-stand pushup.
Also, exploding when you move the weight away from the ground and going really slowly when you release it back towards the ground makes the weight feel a lot heavier.
