Question: is it safe to run on this? or just jogging?
Document: I use this weighted vest at home on days I don't go to Crossfit. It is great for jogging, doing lunges, or doing pushups on pushup bars which allow me to go lower to allow room for the vest. It's very well made and thankfully has two straps to keep it from moving too much when I run. Excellent product for the money.
i love this vest, but it isn't meant for jogging or exercises that includes jumping ( plyometrics).but i do recommend this vest.
If just walking and jogging, start with 20lbs. Wait weeks till your muscle and joints (especially the knees, they are fragile) getting used to your new "bodyweight". If doing jumping or sprinting, start with 10lbs please...... With these sudden movements, great acceleration would make 10lbs feel much heavier. Form and quality of your movements are much important than those mere numbers of the weights.
For anybody wanting to get a great workout, get one of these weighted vests. The 40 pounds of weights that it comes with can be adjusted however you want it. Lighter weights for any workout, jogging, yardwork, etc. Have the heavier weights put on the vest and just wear it under your jacket for the day. Talk about feeling like Superman when you are finished. A great way to increase any workout.
The vest is great! The only problem I have with it is that it hurts my shoulders sometimes when I run.
My son likes to run stairs and sprints for his football workouts. So we invested in this weight vest for him. He says he loves it. No complaints whatsoever.
works great i bought this to condition for my deployment to iraq since our vests are 40 lbs works great no chaffing around the arms during the run highly reccomended
it is what you get. really good vest to work out and put some pounds. can adjust to the weight you want to start with. i used to walk with and run. package was delivered by ups, promptly and neatly.
This is a rugged vest. I like that I can add or remove weight from the vest. It is very adjustable and comfortable. It does bounce a little when you run, but if you tighten the straps. Beware, shipping is very expensive!
The vest bounces dramatically when you run with it, resulting in very sore abs after each run. The fact that it's adjustable in 2.5 lb increments is a plus, but the vest is a bit big and awkward because of that.
Answer: yes
