About this app

Whether you have access to some equipment or just your body weight, Stark Fitness helps you get in shape, and to build muscle and strength. Stark Fitness is well suited for both gym and home training.

CREATE YOUR OWN WORKOUT PROGRAMS
To build your own programs and workouts is easy with drag and drop. Combine exercises with different equipment in the same workout, however you like. Filter exercises by muscle group and tool. With Stark Fitness you can choose from more than 700 exercises across the categories Bodyweight, Barbell, Dumbbell, TRX/Suspension, Kettlebell, Gym Ball, Rip, Vipr, Bosu Ball, Resistance Band, Medicine Ball, Bulgarian Bag and Gym Machines. All exercises have a video where a professional trainer shows you how to perform the exercise with the correct form. In addition to strength exercises, there are also instructions for stretch and warm-up routines as well as Foam Roller exercises for recovery.

PREBUILT WORKOUTS
Get started by choosing a workout from one of the ready-made training programs. From more classic gym workouts for building muscle, to high-intensity tabata workouts focused on training your butt and abs. No matter what training goals you have set, Stark Fitness strives to help you reach them.

QUICKSTART
A quick and easy tool to create variation in your training. Choose if you want to use some equipment or only your body weight, then time and intensity, and a new workout is created!

WORKOUT TIMER
Start a workout, follow the instructional videos and try to keep up with the pace.
For each session, you can configure the timer according to your own goals. Choose between Standard, Tabata, HIIT (high-intensity interval training) or circle training settings.
Standard: Select time or number of repetitions, length of rest, and number of sets.
Tabata: The time is locked to 20 seconds active and 10 seconds rest; select the number of rounds.
HIIT: Select active time, rest time, and number of rounds.
Circle: Select time or number of reps, rest intervals, and number of rounds.

Creating an account is optional, but is required if you want to sync your programs and workouts across multiple devices.

Really good app, espeically when you can't decide what to do, you just pick the equipment you have, pick time and intensity and let the app pick your workout. One star removed as I can't login/register

Great app with good videos and features. For me this app stands out because: * You can create workouts that use different equipment e.g. dumbbells with Swiss ball and TRX * You have control over the style of workout (reps or time, HIIT or Circuit or Tabata) * You have control over transition time from one exercise to another. So many apps only give you 5 or 10 seconds to transition from one exercise to another (which I find far too short) * The app support team is prompt to reply

Excellent app. I initially downloaded the suspension trainer app but switched to this for a more rounded workout selection. The simplicity of the drag and drop set up for creating workouts and grouping them together is fantastic. As is large choice of equipment and exercises available. The ease of changing the duration and intensity is very good. I just wish I had found it earlier.
