We’ve done workouts on the track, splitting the workout so we wore the gloves in the beginning and took them off the last 25% of the workout, with or without spikes this helps the runners feel even faster and more confident.
When I use XtraEdge Gloves on the treadmill my heart rate is 10 pts. higher and my arms always feel tired like I feel after lifting weights.
I swear I burn more calories and I get a lot more out of my 30 min workout.
My arms are definitely getting more toned from wearing XtraEdge two days per week.
