Gym circuit ideas

I have one call the 1000 cal burn if you interested?

I like to do 100s so a set of 25 chest, back, triceps, biceps, shoulders maybe add in abs and back all with hand weights or body weight run 2 laps on the track about 1.5 minutes do another set of 20 or 25s each, run ect till I have done 100 reps with warm up and cool down laps it ends up being about 1.5 miles running with the lifting. I will do the same thing with lower body you can look up exercises online to target specific muscle groups. You can do this same type of thing but do each exercise 45 seconds, with a 15 second rest for 8 different exercises then do my lap or 2 rest 1-2 minutes and repeat should do 3 or 4 complete sets in 45 min. Sample:
Chest: chest press or push ups
Back: bent over rows
Shoulder: shoulder press, flys, arm circles
Biceps: curls different variations
Triceps: dips, overhead extension, tricep push-ups
For 100s I would do one out of each section 25 reps. If I were doing 45 second workout I would space some mountain climbers, jumping jacks, plank jacks, and curl ups, bicyclers not sure the real name in there for a total of 8 different exercises. If I want to go lower body I would just switch out lower body exercises. of course , I just gave the upper body workouts and cardio stuff but anyway you get the idea. I switch it up a lot. Used to do a boot camp class one summer so learned lots of different exercises but there are resources online too. Sorry so long hope that makes sense.

Its a simple body weight circuit.
