1. Staircase Workouts ? This is great because stairs are everywhere. Try mixing stairs sprints with an upper body exercise like pushups or pull-ups. If done with a high enough intensity, stairs workouts help to create changes throughout your entire body due to the muscle building and fat burning hormonal response and metabolism increase that you get through working the biggest muscle groups in your entire body.
2. Wind Sprints and Hill Sprints - Find any open field in a park or athletic field and try 50, 75, and 100-yard all-out wind sprints. After each sprint, rest long enough to catch your breath before the next one (generally 1-2 minutes).
3. Kettlebell Training ? is an alternative type of free-weight training instead of barbells and dumbbells. Their unique construction and weight distribution (basically a cannonball with a handle) allows for a whole different realm of exercises that?s available compared to dumbbells and barbells.
4. Bodyweight Workouts ? These can be great because you can get a high intensity workout done in only 15-30 minutes without having to go to the gym on days that you might not have time for a trip to the gym. Try alternating bodyweight squats, pushups variations, lunges, and floor abs exercises continuously for 15-30 minutes.
5. Ring Training ? You throw the straps up over any high bar like a pullup bar, the top of a power rack, or even over a football field goal crossbar. Then you can quickly adjust the rings to do exercises like ring dips, ring pushups, ring pull-ups, hanging leg raises, horizontal body rows, L-sits, and more. Dips and pushups on the rings are my favorites and the rings really make them a hell of a lot more difficult, while also incorporating your stabilizer muscles to a much greater degree. The rings allow your joints to move in a more natural pattern and can help you prevent or even recover from shoulder injuries.
6. Swimming ? A great full body workout that stresses the muscles and joints in a much different way than most resistance training. Incorporating swimming workouts once or twice a week into your normal training routings can really enhance your physique.
7. Sandbag Training ? It works your body with an unstable object, which makes muscles that might normally be neglected get in on the action to perform the movements. Sandbag exercises can be done as squats, cleans, presses, lunges, shouldering, throws or heaves, carrying up hills, etc.
8. Mountain Biking ? You get the leg pumping exertion during the uphill climbs, while also getting the adrenaline rush of the downhill acting as your recovery intervals. Mix it all together and you get a super-fun, high-intensity, leg burning workout that will melt fat off of your entire body and build awesome legs at the same time. The climbs can be tough and will challenge you both physically and mentally as you pump away trying to make it up steep hills without having to resort to getting off of the bike.
9. Indoor (or outdoor) Rock Climbing - Indoor rock climbing gyms have starting popping up all over the place in recent years and will be more accessible than outdoor rock climbing to most people. Rock climbing is a great workout for your legs, arms, shoulders, and your entire back. It also really works your grip strength and forearms like crazy.
10. Stick Wrestling ? This is a killer full body workout and can also be a great competition between you and your friends. This is probably more of a guy thing for most.
11. Strongman Training ? This type of training is a little more hard-core, but it?s a blast for those who are into trying something different. The premise is based on the types of exercises competitors perform in the ?worlds strongest man? competitions. If you have a yard, you can even set up some of these exercises in your yard and do some outdoor workouts to have a little fun. You can get one of those giant tractor tires and do tire flips (which is basically a deadlift followed by a push-press).
12. Rope Climbing - A great way to incorporate rope climbing into intense workouts is to do a climb up, then lower yourself back down. Then while your upper body is recovering for the next climb, you can do a lower body exercise like squats or lunges, or go up and down stairs. Keep alternating the upper body rope climbs with the lower body exercises in between and you?ll get one hell of a full body workout.
13. Bag Boxing ? You can use a heavy bag, a speed bag, or even one of those rebound bags to get a great workout. Among the three, the heavy bag is the best all around full body workout, while the speed bag will test your rhythm and timing and give you a great upper body workout. If available at your gym or if you have a bag at home, try mixing these in as a good warm-up or as an intense finish to your strength routine.
14. Rope Skipping ? You can?t beat rope jumping as a great full body exercise. Try mixing together two legged jumps, one-legged jumps, arm crossovers, double jumps (rope passes under feet twice for each jump) to keep things interesting and increase the intensity. Also, try alternating 15-20 second high intensity bursts where you jump as fast as you possibly can, followed by 15-20 second recovery intervals where you jump slowly to get ready for your next burst. Keep repeating until you?re whooped.
15. Jumping exercises ? squat jumps, box jumps, lunge jumps, and broad jumps are some of the best ways to incorporate explosive jumping exercises into your routines. The explosive and powerful nature of jumping exercises works your leg muscles in an entirely different way than most normal slow grinding strength training moves.
