During a workout, we perform exercises. Each exercise is characterized with parameters, like weight and reps, or time and distance, etc.

Everything is quite transparent, but just in case, here are examples of parameters and exercises that can be described with such parameters:

Weight & Reps: Barbell Squats, Machine Leg Extensions
Time & Distance: Running, Rowing
Reps only: Push-Ups, Box Jumps, Crunches, Rope Climbs
Time only: Plank, Rope Jumping, 100 meter Run, Battle Ropes
Weight & Time: Farmers Holds, Weighted Plank
Weight & Distance: Farmers Walk, Sled
Reps & Time: Burpees, Tire Flipping

Also, the exercise may have properties that help calculate the correct metrics, such as training volume or one-rep max. If the exercise has such properties, this affects the numbers that are entered in the parameter fields. These properties and their meaning are listed below.

Weight x 2
Let's imagine that you've performed a set of a shoulder press - 10 reps with 50 lbs dumbbells. The most common and intuitive way to write it down is 50 lbs x 10 reps, and we suggest using this way. But actually, you've lifted 100 pounds in each rep, 50 pounds in each hand. The Weight x 2 property indicates this.

Unilateral
Let's imagine that you've performed a set of lunges - 12 reps for each leg with a 120 lbs barbell. You can write it down as 120 lbs x 12, and we suggest using this way. But actually, you made 24 reps, 12 on each leg. "Unilateral" feature is used to indicate this.

If you prefer to record the total number of reps in a set (24 in the example above), do not mark an exercise as unilateral.

Bodyweight
This property is applied to exercises that use near 100% of the body weight as resistance, such as Pull-Ups or Dip.

Let's imagine that you've performed a set of pull-ups: 10 reps with additional weight (let it be a 16 kg kettlebell). Obviously, the main resistance was provided not by a kettlebell but by the weight of your body. "Bodyweight" feature is used to indicate this.

For Time
This feature is used to indicate that the shortest time is the best.
