How to prevent race condition in this case laravel 11

I have a table named gym_sessions it has user_id | status columns. status column can contains: 1 ==> active; 2 ==> completed; 3 ==> declined;

Conditions:

• User must have sufficient balance to start new session.
• User can't have two active sessions at the same time.
• User can have many sessions of status: 2 | 3;

This is my method for creating new session for a user:

// Start new gym session.
    public function startGymSession(Request $request){
        $validator = Validator::make($request->all(),[
            'gym_id'                => ['required', 'exists:gyms,id'],
            'payment_method_id'     => ['required', 'exists:payment_methods,id'],
            'gym_pricing_id'        => ['required',
                Rule::exists('gym_pricings', 'id')->where(function ($query) use ($request) {
                    $query->where('gym_id', $request->input('gym_id'));
                }),
            ],
        ]);
        if($validator->fails()){
            return $this->sendError('Validation error!');
        }

        $user = Auth::user();

        // Check if the user have enough balance to start a gym session.
        $userbalance = $user->wallet_balance;
        $gymPricing = GymPricing::find($request->gym_pricing_id)->first();
        if($userbalance < $gymPricing->price){
            return $this->sendError('Insufficient balance.');
        }


        // Check if the user have active gym sessions.
        // If the user have active gym sessions, he can't start a new one.
        // Prevent race condition.

        /** @var \App\Models\User $user */
        if($user->gymSessions()->where('status', 1)->count() > 0){
            return $this->sendError('You have an active gym session.');
        }

        $now = Carbon::now();

        // Start the gym session.
        $gymSession = GymSession::create([
            'user_id'       => $user->id,
            'gym_id'        => $request->gym_id,
            'payment_method_id' => $request->payment_method_id,
            'gym_pricing_id'    => $request->gym_pricing_id,
            'entry_time'        => $now,

        ]);
        if($gymSession){
            return $this->sendResponse([], 'Gym session started.');
        }


        return $this->sendError('Failed to start gym session.');
    }

Attack Scenario:(Race Condition) If the user sent multiple requests in parallel, the system will create many sessions with status 1.

I want to know how to prevent this problem on application level (using Laravel methods) not on database level?
