Exercising with a friend makes the fitness session more like intense social time!
Whether you exercise alongside someone in the flesh, or simply compare results over an app, by using the personal challenge alongside the very human need to come first (!) you get that extra set of squats completed, run that extra kilometre and feel all the more satisfied in the end.
It all works alongside ENJOYING yourself when following your fitness routine. By making sure that an exercise session is fun and not a chore will lead to better results and keep you training when you may otherwise throw in the towel.
…Of course, like with all personal experience, YMMV. But I always find closing my training sessions alongside my exercise friends a great motivator – especially if we cool down at the bar!
