The exercises listed below are excellent for beginning students.

1. A Dumbbell Farmer’s Walk accompanied by a Towel

What Do I Do This: This exercise requires two small towels (For instance, the width is 14 inches and the length 22 inches long). Wrap one towel over the dumbbells’ grip and grasp each towel’s ends. Stand in a straight position with shoulders back. Run 25-50 yards around your gym’s flooring or outside. You could also make use of weight plates for this workout. When the plates have multiple openings, for example, one at the top and one at the middle, you can loop the towel through the top hole and hang it from there. A more oversized towel might be required to wrap around the center hole on a 25-35 or 45lb plate.

2. Dead Hang

How To Do This: Grip a pullup bar or any other sturdy overhead structure using the pronated (overhand grasp). The scapula should be lifted slightly to activate your core and stimulate your back muscles. Try to hang for 15 seconds, followed by 30, 45, and then 60 minutes. When you’re able to stay for 60 minutes, you’re able to play around with your hands horizontally while hanging by moving between sides on the bars.

3. Fat Gripz Dumbbell Curl

How to Use it: You can use a Fat Gripz, Harbinger Big Grip, or any other rubber device that adds weight to a dumbbell or barbell or the exercise. These grip-enhancing devices are suitable for a range of strength training exercises. However, using the Fat grips on the curl of a dumbbell emphasizes how important biceps and forearm strength are to compete in the Spartan Race.

Place one Fat Gripz on one of the dumbbells’ handles. Hold each dumbbell with a supinated (palms in front) grip. Standing with your feet separated by shoulder width and the shoulders back, bend the dumbbells up to chin height and keep the wrists straight and hands up all the duration. Return the hands to their starting position. It is one rep.

4. Barbell Shrug

What you can Do: You can shrug a straight barbell, trap bar dumbbells, or even a device to enhance Grip Strength. However, the barbell shrug is the workout you must include in your conditioning and strength routine to increase grip strength.

Barbells should be held using the pronated (overhand) grip that is shoulder-width between your hips with your arms straight. Keep the barbell on your back while your arms are back and your head in front. This is your starting point. Keep your hands straight, and extend your shoulders and traps towards the ceiling. Pause for three seconds, and then bring the weight back to the starting position.

5. Deadlift

What Do I Do it:. To use the deadlift for grip strengthening, make sure not to utilize the alternated (right hand over left hand underneath grip) at ALL during your set. If you find that the weight is becoming too heavy that you are forced to use an alternate grip, your goal has been changed to absolute strength rather than grip strength. Additionally, you can deadlift within an 8-10 rep area while working on your grip.

6. Reverse Barbell Wrist Curl

How to Perform the exercise: This exercise is solely to build the endurance of the forearm muscles that will allow you to complete the above Spartan challenges. Take a barbell and place it in an overhand grip in front of you so that it is about a foot of your back. As you maintain an upright position, allow the barbell to slide onto your fingers, then with your arms straight (not bent). Then, you’ll need to make an arm fist, then contract your arms to grip the bar once more in a tight grip. It’s a single repetition,

7. Resisted Hand Opening

How to Use it:Touch every one of your fingers so that your the thumb is touching the tips of the remaining four fingers. Join a rubber band with finger closed, the band must pushed against your fingers for better result, the exercise would look like someone is doing high-five. Then, bring fingers back together. This is one rep.

8.Pinch Grip Plate Secures

How to Perform it:This exercise trains the capacity to hold something for a long duration of time. Set a 10-pound plate (or larger for athletes who are more advanced) directly upon the ground. Place a bench or a box near. If the plate can stand on its own, let it raise itself. Hold the plate using your right hand, using only your fingers, not wrap your hand around it. This means that your thumb is only on one part of the plate, and the remaining four fingers are on the opposite side. You should stand straight with the plate by your side. Take a 5 second break, then put the plate back on the bench or box. Repeat 5-10 times

All of the above are very good exercise for developing grip strength. You can add squeeze exercise with  hand grip strengthener ball for better result.
