Not everyone likes having someone hold them accountable. Its not always “fun” or “comfortable,” but at the end of the day if you can’t hold yourself accountable for your goals it might just be the best option. Remember your “why” and the end goal.
Also, not everyone wants to workout with someone for various reasons, but you may just be overthinking it. Even if you do not want to have someone work in with you or are worried about doing their workout, you don’t have to. Sometimes it can be motivating if you have a workout/accountability partner that motivates you to get to the class, park, or gym (because we all know thats half the battle) and work out at the same time. This can sometimes help push you for that last rep or the last 5 minutes of cardio you do not want to do, just seeing them there with you.
