Tan- I started with 100s too. Then we had “steel suitcases” made out of pieces of railroad beams. We just welded fat handles onto them basically.
You’re right about Monday. I did that a few times and had to skip Monday’s workout because I overdid the dino day. Now I can usually work around any problem. For example, if I’m doing legs on Monday then I’ll try not to hit them much on Sunday. (No truck pushing and pulling or squats with kegs, in other words.) Not going all the way to failure helps, too. Ideally, it is a good idea to take off the day before and the day after a dino day. You could also just use one “finisher” after each workout, just monitor your recovery.
If the movement is explosive and requires balance and stability (clean and presses with a half filled keg) you could even do that before your regular workout.
I really like this functional aspect to strength training and would advise everyone to incorporate some of this stuff into their training. I’ve noticed I feel really solid in my regular exercises when I’m consistant with my dino stuff. After all, if you can walk up stadium steps with a sloshing keg of water, then barbell lunges are no problem.
