Developed for PostgreSQL 9.
First create a new database:
$ createdb training
Then run the main SQL script:
$ psql -f db/main.sql training
This will install all SQL tables. Open the database with psql:
$ psql training
Once in the database list all existing schemas:
training=# \dn
Liste der Schemas
Name | Eigentümer
----------+------------
log_1708 | nils
(1 Zeile)
Pick the most recent one:
training=# set search_path = log_1708;
To see all tables use \dt:
training=# \dt
Liste der Relationen
Schema | Name | Typ | Eigentümer
----------+------------+---------+------------
log_1708 | t_sets | Tabelle | nils
log_1708 | t_workouts | Tabelle | nils
(2 Zeilen)
For more information on a table use \d, e.g.:
training=# \d t_workouts
Tabelle »log_1708.t_workouts«
Spalte | Typ | Attribute
-----------+-----------------------------+-------------------------------------------------------------
id | integer | not null Vorgabewert nextval('t_workouts_id_seq'::regclass)
timestamp | timestamp without time zone | not null Vorgabewert now()
title | text |
Indexe:
"t_workouts_pkey" PRIMARY KEY, btree (id)
Fremdschlüsselverweise von:
TABLE "t_sets" CONSTRAINT "t_sets_workout_id_fkey" FOREIGN KEY (workout_id) REFERENCES t_workouts(id)
training=# \d t_sets
Tabelle »log_1708.t_sets«
Spalte | Typ | Attribute

id | integer | not null Vorgabewert nextval('t_sets_id_seq'::regclass)
workout_id | integer |
exercise | text |
sets | integer | not null Vorgabewert 1
reps | integer | not null Vorgabewert 1
weight | double precision | not null
failure | boolean | not null Vorgabewert false
Indexe:
"t_sets_pkey" PRIMARY KEY, btree (id)
Fremdschlüssel-Constraints:

To add a new workout, simply INSERT a new row into t_workouts with default values:
training=# insert into t_workouts default values returning id;
id
----
1
(1 Zeile)
INSERT 0 1
Then add all workout sets to this workout ID, again using INSERT:
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, '3x clean + jerk', 60, 3, 2);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, '3x clean + jerk', 70, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, '3x clean + jerk', 75, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, '3x clean + jerk', 80, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, '3x clean + jerk', 85, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'c&j', 90, 1, 2);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'jerk from rack', 60, 3, 2);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'jerk from rack', 65, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'jerk from rack', 70, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'jerk from rack', 75, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'fsq', 60, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'fsq', 100, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'fsq', 110, 3, 1);
training=# insert into t_sets (workout_id, exercise, weight, reps, sets) values (1, 'fsq', 120, 3, 1);
And eventually display all data using SELECT:
training=# select * from t_sets where workout_id = 1;
id | workout_id | exercise | sets | reps | weight | failure
----+------------+-----------------+------+------+--------+---------
1 | 1 | 3x clean + jerk | 2 | 3 | 60 | f
2 | 1 | 3x clean + jerk | 1 | 3 | 70 | f
3 | 1 | 3x clean + jerk | 1 | 3 | 75 | f
4 | 1 | 3x clean + jerk | 1 | 3 | 80 | f
5 | 1 | 3x clean + jerk | 1 | 3 | 85 | f
6 | 1 | c&j | 2 | 1 | 90 | f
7 | 1 | jerk from rack | 2 | 3 | 60 | f
8 | 1 | jerk from rack | 1 | 3 | 65 | f
9 | 1 | jerk from rack | 1 | 3 | 70 | f
10 | 1 | jerk from rack | 1 | 3 | 75 | f
11 | 1 | fsq | 1 | 3 | 60 | f

All workouts are listed in the t_workouts table:
training=# select * from t_workouts;
id | timestamp | title
----+----------------------------+-------
1 | 2017-08-08 22:37:37.308922 |
(1 Zeile)
To add a title to the workout, UPDATE the corresponding row:
training=# update t_workouts set title = 'The first workout' where id = 1;
training=# select * from t_workouts;
id | timestamp | title
----+----------------------------+-------------------
1 | 2017-08-08 22:37:37.308922 | The first workout
