Want to do trainings, but no weights. No problem! Use your body weight. Fix a muscle/s day, or a strategy i.e. PUSH-PULL-LEG. For chest, pus-up & tricep variations will help. Use bench / chair, broom stick, water buckets & water gallons and wall / door pull ups for lats & back. Jump squats, lunges and cal raises for lower body.
Please find workouts in this program that are bodyweight only - https://grokker.com/fitness/program/21-day-athlete-level-up/5d0288ca3859ac2f1eb7bcb5 and https://grokker.com/fitness/abs-and-core/program/4-week-core-program-with-sam-skelton/57571803cc5f6ce437c5bb75
