There’s nothing wrong with TBT training, but this setup is kinda crap.
First off, if you are going to do TBT 3x per week, each workout SHOULD NOT be exactly the same. This may work if you are a complete beginner and cant push yourself, but for everyone else, their needs to be some variation. Also, even though it migh be TBT you aren’t usually going to train each movement with the same emphasis on the same day.
Some days will lean more toward an upper body day, or a push day, and some days will be opposite. Lastly, in a TBT plan, there is LESS exercises you get to choose as opposed to any other plan. This means you need to choose the very best for the job. Their is no room IMO for bridge press and rollouts.
A better setup with what you were working with would look like this:
Workout A:
1a) Back squat
1b) Standing press
2a) Row
2b) RDL
3a) Lunges
3b) Shoulder raise
Workout B:
1a) Bench OR floor press
1b) Deadlift
2a) Pullup
2b) Triceps
3a) Front squat
3b) Biceps
If doing this, I would go with at least 3-5 sets of 3-12 reps, depending on what you are trying to accopmlish. You could also change the rep/set scheme depending on the day or the exercises. Sometimes 5x5 and sometimes 3x10, etc.
This CAN work very well and if a good setup for all around fitness. You can build muscle, strength, endurance etc, on this but it has many shortcomming if you want to focus on one quality.
If you are looking for maximal strength or muscle mass, supersets are NOT the way to go. You simply wont have the lung capacity to push heavy enough on the weights to progress. But if you are looking to build a good base, and decent muscle/strength health and endurance, then this is a good way to go.
