This could be a results of multiple things but most commonly we see people are lacking progressions during sessions and training where comfortable on exercises rather than pushing themselves. Are you a victim of this? 
It may be that you have consistently been using an 8kg kettlebell during sessions and this is great as you are able to do a range of movements with this and get lots of reps completed in a given workout, but could you perhaps increase that now to a 10kg kettlebell instead? 
Not progressively overloading your training can be a huge factor when it comes to hitting a plateau. You need to constantly be changing and challenging your body so that you develop the muscle over time. 

So what is progressive overload and how do you implement it into training at bootcamps? 

Progressive overload is when you gradually increase the amount of stress put on the muscular skeletal and nervous system to stimulate muscle growth and strength. This is done by progressing the weight used or amount of reps completed in your session. 
How would this look in bootcamp – Instead of using 15kg bar and completing 15 reps, why not take it to 20kg barbell and complete 10 reps, when you get to the 10 reps if you could have done another 2-3 more reps, then increase that 20kg up to 22.5kg. 

Overtime, the heavier weight option will feel lighter and you will be able to complete a few more reps, therefore you would then increase that weight again. 

This means your body is constantly having to work to deal with the stress placed upon it, and therefore increase your muscular strength and endurance. 

A benefit of having more muscular strength and composition, the higher your metabolism at rest so you can burn more calories and reduce your body fat percentage when coupled with a balanced healthy diet.
