A few of you are mentioning home gymming. Here's some things I've been doing. I have no equipment, but my wife has a pair of 24 lb powerblocks.
Legs:
Squats: I wear a weighted backpack, my wife wears one on the front, I lift her in my arms and do sets of 9 (~220 lbs)
Bulgarian split squats: Hold 24 lb powerblocks in each hand and a 22 lb backpack, legs burn at 18 reps.
Single leg romanian deadlift. Sets of 20 burn with only 48 lbs if I go deep.
Pistol squats, unweighted.
Nordic curls, assisted by pushing off the ground a bit.
Upper body is probably not as interesting for cyclists:
Shoulders:
Handstand pushups
Feet elevated pike pushups
Lateral raises (doesn't take much weight, I bet gallon jugs would work).
Chest:
dips on the back of a bleacher (park next door, but 2 stools would work)
Feet elevated, pseudo-planche pushups
One arm push ups
High rep pushups
Back:
Pull ups
Tuck front lever rows
Inverted row variations
Bent over reverse flys
